TO: Administrative Rules Coordinators and Text Processors of State Agencies

FROM: Kathleen K. Bates, Iowa Administrative Code Editor

SUBJECT: Publication of Rules in Iowa Administrative Bulletin

The Administrative Code Division uses Interleaf 6 to publish the Iowa Administrative Bulletin and can import documents directly from most other word processing systems, including Ami Pro, Microsoft Word, Professional Write, Word for Windows (Word 7 or earlier), and WordPerfect.

1. To facilitate the processing of rule-making documents, we request a 3.5" High Density (not Double Density) IBM PC-compatible diskette of the rule making. Please indicate on each diskette the following information: agency name, file name, format used for exporting, and chapter(s) amended. Diskettes may be delivered to the Administrative Code Division, 4th Floor, Lucas State Office Building or included with the documents submitted to the Governor's Administrative Rules Coordinator.

2. Alternatively, if you have Internet E-mail access, you may send your document as an attachment to an E-mail message, addressed to both of the following:

bcarr@legis.state.ia.us

kbates@legis.state.ia.us

Please note that changes made prior to publication of the rule-making documents are reflected on the hard copy returned to agencies by the Governor's office; diskettes are returned unchanged.

Your cooperation helps us print the Bulletin more quickly and cost-effectively than was previously possible and is greatly appreciated.

ARC 7652A

Pursuant to the authority of Iowa Code section 455B.172, the Environmental Protection Commission hereby gives Notice of Intended Action to rescind Chapter 49, "Nonpublic Water Wells" and Chapter 69, "On-Site Wastewater Treatment and Disposal Systems," Iowa Administrative Code, and adopt Chapter 49 and Chapter 69 with the same titles, and to amend Chapter 60, "Scope of Title--Definitions--Forms--Rules of Practice," and Chapter 64, "Wastewater Construction and Operation Permits," Iowa Administrative Code.

Chapter 49, "Nonpublic Water Wells," has not undergone major updating since before it was moved to the Department's jurisdiction from the Department of Public Health in 1983. Starting in late 1995, a technical committee of the Iowa Groundwater Association reviewed the rules and suggested revisions. Meetings with well drillers from the Iowa Water Well Association and sanitarians from the Iowa Environmental Health Association were then held to incorporate industry and other regulatory points of view.

The impetus to review Chapter 69, "On-Site Wastewater Treatment and Disposal Systems," came primarily from state legislators desiring to provide counties more flexibility to deal with difficult sewage disposal situations. Also, significant new technology is being introduced into the state which has created a need for rule changes. An advisory committee of legislators, county supervisors, private contractors and county sanitarians was established to review this rule and recommend revisions. The revised rules are a culmination of this effort and include input by the Iowa Environmental Health Association.

Any interested person may provide written comments on these amendments on or before December 23, 1997. Comments should be submitted to Brent Parker, P.E., R.S., Iowa Department of Natural Resources, Wallace State Office Building, Des Moines, Iowa 50319-0034. Interested persons are also invited to present oral or written comments at public hearings which will be held at the following locations:

"Pitless adapter" means a device designed for attachment to one or more openings through a well casing. It shall be constructed so as to prevent the entrance of contaminants into the well through such openings, conduct water from the well, protect the water from freezing or extremes of temperature, and provide access to water system parts within the well.

"Pitless unit" means an assembly which extends the upper end of the well casing to above grade. It shall be constructed so as to prevent the entrance of contaminants into the well, conduct water from the well, and protect the water from freezing or extremes of temperature, and shall provide full access to the well and to water system parts within the well. It shall provide a pitless well cap for the top terminal of the well.

"Public water supply" means a system for the provision to the public of piped water for human consumption, if such system has at least 15 service connections or regularly serves an average of at least 25 individuals daily at least 60 days out of the year. The term includes (1) any collection, treatment, storage, and distribution facilities under control of the supplier of water and used primarily in connection with the system; and (2) any collection (including wells) or pretreatment storage facilities not under the control of the supplier which are used primarily in connection with the system.

Replacing a screen with one of identical diameter and length, replacing a pitless adapter, or acidizing a well would be considered repair, not rehabilitation or reconstruction.

"Runoff control basin" means an impoundment designed and operated to collect and store runoff from an open feedlot.

"Shallow well" means a well located and constructed in such a manner that there is not a continuous layer of low permeability soil or rock (or equivalent retarding mechanism acceptable to the department) at least 5 feet thick, the top of which is located at least 25 feet below the normal ground surface and above the aquifer from which water is to be drawn.

"Stuffing box" means an approved receptacle in which packing may be compressed to form a watertight or airtight junction between two objects.

"Well" means any excavation that is drilled, cored, driven, dug, bored, augered, jetted, washed or is otherwise constructed for the purpose of exploring for groundwater, monitoring groundwater, utilizing the geothermal properties of the ground, or extracting water from or injecting water into the aquifer. "Well" does not include an open ditch, drain tiles, an excavation made for obtaining or prospecting for oil, natural gas, minerals, or products mined or quarried, lateral geothermal heat exchange systems less than 20 feet deep, nor temporary dewatering wells such as those used during the construction of subsurface facilities only for the duration of the construction.

"Well seal" means a device used to cover or seal a well that establishes or maintains a junction between the casing of the well and the piping, electric conduit or equipment installed, so as to prevent water or other foreign material from entering the well at the uppermost terminal.

1. "Well cap" means a snug-fitting, watertight device used above flood level that excludes dust and vermin and allows for screened venting.

2. "Sanitary seal" means a watertight fitting which uses mechanical compression that is installed on wells that terminate in a well house.

"Well services" means new well construction, well reconstruction, installation of pitless equipment, or well plugging.

567--49.3(455B) Applicability. The provisions contained herein apply to all nonpublic water supply wells constructed for the purpose of domestic, livestock, irrigation, recreation, and commercial or industrial use, that are completed after the effective date of these rules. They shall also apply to existing water wells undergoing rehabilitation or reconstruction.

Ponds and surface water supplies are not covered by these standards. Information regarding use of these sources of water should be sought from the administrative authority prior to the development of the sources.

49.3(1) Nonconforming installations. Certified well contractors shall ensure that the rehabilitation or reconstruction of nonconforming wells adheres to all applicable provisions of this chapter or to comparable construction or installation requirements approved by the administrative authority.

When any construction or reconstruction is done on a nonconforming feature of a well, that feature shall be upgraded and brought into compliance with the material and installation standards contained in this chapter.

49.3(2) Exemptions. This chapter shall not apply to public water supply wells, horizontal heat pump installations, elevator shafts, underground storage tank monitoring wells as covered under 567--Chapter 135, or monitoring wells for solid waste disposal facilities as covered in 567--Chapter 110.

567--49.4(455B) General. The administrative authority shall have the authority to visit well sites during any phase of the work without prior notice. The administrative authority shall by rule require the issuance of permits and the submission of water well logs. No well services shall be initiated until a permit has been issued by the proper authority. Theadministrative authority may also require posting of performance bonds and collection and submission of other data. The issuance of permits is covered in 567--Chapter 38 and shall be coordinated with the water withdrawal permits issued by the Iowa department of natural resources as covered in 567--Chapters 51 and 52. All well services shall be performed by a certified well contractor or the property owner as specified in 567--Chapter 82.

It shall be the responsibility of the certified well contractor to ensure that a well construction permit has been issued prior to initiation of well services. It shall also be the responsibility of the certified well contractor to ensure that all well services are performed in accordance with the provisions of this chapter.

567--49.5(455B) Variances. Variances to these rules may be granted by the administrative authority if sufficient information is provided to substantiate equal protection and the need for such action. Variance requests and reasoning shall be in writing. Variance approvals or rejections shall also be in writing. Where permitting authority has not been delegated to the county, the department will review and grant or deny any variance requests within that jurisdiction.

567--49.6(455B) Location of wells. Wells shall be located with consideration given to the lot size, contour, porosity and absorbency of the soil, local groundwater conditions, flooding, and other factors necessary to implement the rules. The lack of specific distances to other possible sources of contamination, such as refuse disposal sites and high-pressure gas lines, does not minimize their potential hazard. These must be evaluated in each particular situation and a distance arrived at that is based on pertinent facts. The well contractor shall consult the administrative authority for assistance in determining a proper distance in such cases.

49.6(1) Minimum distances. The following minimum lateral distances shall apply for the common sources of contamination listed in the following table.

49.6(2) Exception to minimum lateral distances. The minimum separation distance between a well and an anaerobic lagoon, earthen manure slurry storage basin, earthen manure storage basin, or runoff control basin shall be 400 feet if the lagoon or basin was permitted by the department after January 1, 1989, or if the applicant demonstrates through percolation testing that the seepage loss through the lagoon or basin does not exceed 1/16 inch per day (0.0625 inch/day). The percolation test shall meet the requirements of ASTM-1587 and 567--subrule 65.15(11).

49.6(3) Relation to buildings. The well shall be located so that no building interferes with reasonable access for cleaning, treatment, repair, testing, inspection and other maintenance. Wells shall not be located in basements.

49.6(4) Easements. No well shall be located on a property not owned by the well owner unless an easement allowing such placement is reviewed and approved by the administrative authority and the easement is legally recorded.

567--49.7(455B) General construction requirements. Wells shall be planned and constructed to adapt to the geologic and groundwater conditions of the proposed well site to ensure reasonable utilization of every natural protection against contamination of the water-bearing formation(s) and the exclusion of possible sources of contamination, to attempt to produce bacterially safe water which is free of health-related problems.

49.7(1) Water used in construction. Water used in the construction process shall be obtained from a potable water source that will not result in contamination of the well. Water used for drilling shall be treated with 3 pints of 5.25 percent sodium hypochlorite solution per 100 gallons of water or 0.25 pounds of 65 percent calcium hypochlorite per 100 gallons of water or other additives to produce an equivalent concentration of chlorine residual (50 ppm).

49.7(2) Wellhead. The upper terminal casing of all wells shall extend at least 12 inches above established grade or pump-house floor, or the 100-year flood level, whichever is higher. A well cap or sanitary seal shall be installed immediately following well completion. A well cap shall be used on an exposed well, a sanitary seal only on a well terminating within a well house. Any openings in the cap or seal, such as for pump wiring or water depth measurement, shall be properly grommeted or sealed except properly screened and oriented vent openings.

The ground surface immediately adjacent to the well casing shall be compacted and graded so that surface water is diverted away from the casing. Well platforms are not recommended other than those used as pump-house floors as indicated in 49.12(2).

49.7(3) Criteria for well interference protection. 567-- Chapter 54 provides an administrative process for owners of nonregulated wells to receive compensation for well interference caused by permitted uses. To be eligible for compensation due to well interference, nonregulated wells constructed after July 1, 1986, must be constructed to allow for some potential well interference.

Allowance for potential well interference is accomplished by constructing a nonregulated well to anticipate a lowering of the static head of the well which may be caused by interference from a nearby permitted use well.

a. The well must be drilled deep enough to allow for setting the pump at least 10 feet or half the normal pumping drawdown, whichever is greater, below the initial recommended setting depth.
b. If the well draws from an unconfined aquifer, the static water level may drop to half the saturated thickness of the aquifer before well interference is considered, if the calculation in "a" above should indicate a shallower depth. Shallow aquifers that are only slightly confined may be classified as unconfined aquifers for this purpose.

The well design also needs to consider drought and reduced well efficiency. (Additional information is contained in 567--Chapter 54.)

A well that is used to withdraw more than 25,000 gallons of water per day requires a water use permit from the Iowa department of natural resources. Upon obtaining such a permit, the well is called a permitted use. If a permitted use exists prior to the construction of a well without a water use permit, no compensation for well interference will be allowed unless a significant change in the permitted use occurs. A physical change to withdrawal facilities may be considered a significant change to a permitted use (e.g., moving the withdrawal location, installing a new well, or installing a higher capacity pump). A person desiring to construct a well not requiring a water use permit should first obtain information concerning nearby permitted use wells. The department of natural resources will provide information on permitted use wells upon request.

49.7(4) Access port for measurement of water levels. Permitted use wells shall be equipped with an access port having a minimum diameter of 3/4 inch. The access port shall be fitted with a threaded cap or plug and be located to allow insertion of a steel tape or electric probe into the well for measurement of water levels. When a spool type of pitless adapter is used which obstructs clear access to the water, a 3/4-inch pipe shall be attached to the spool and brought to the surface below the well cap to allow water level measurements. Wells not requiring a water use permit should be constructed with an access port for water level measurement for possible future well interference concerns.

49.7(5) Interconnection of aquifers. There may be local confining beds that serve an important protective function. Permitted use wells shall use casing and grouting to maintain a hydraulic separation between distinct aquifers separated by confining intervals. Extreme caution should be exercised in the construction of non-permitted use wells if allowing the well to connect aquifers across confining intervals, particularly in areas where that would open the aquifer to surficial contamination, i.e., in areas where the upper rock unit is unconfined or contains less than 40 feet of unconsolidated materials. The administrative authority shall be consulted for possible local regulations when interconnection of aquifers across confining intervals is anticipated.

567--49.8(455B) Types of well construction.

49.8(1) Drilled wells.

a. Drilled wells in unconsolidated materials.

(1) Depth. In no case shall less than 20 feet of permanent casing be installed in wells drilled in unconsolidated materials. If the alluvial aquifer where the water is to be drawn from is covered by less than 40 feet of low permeability materials, the well screen shall be set at the bottom of the water-bearing aquifer or at least 60 feet from the surface. (Deeper depths may be required if nitrate contamination is excessive.) If more than 40 feet of low permeability materials are present above the aquifer, the casing shall extend down at least to the top of the aquifer.

(2) Grouting. Grout shall be placed to a minimum depth of 40 feet or along the full length of the casing where less than 40 feet of casing is set. Grouting the full length of the casing below 40 feet may be necessary to isolate any undesirable contaminated water lenses or aquifers. If a layer of low permeability material at least 5 feet thick is encountered less than 40 feet from the surface, the grout may be terminated at least 5 feet below the top of this low permeability material, but in no case less than 20 feet from the ground surface. Grout must be placed in accordance with 49.9(3), except when driving casing. When driving casing a #8 mesh bentonite or bentonite grout must be maintained around the outside of the casing. The bottom of driven casing must be equipped with a drive shoe.

(3) Annular space. The diameter of the borehole shall be at least 3 inches greater than the outside diameter of the well casing to the minimum grouting depth. When steel well casing pipe is installed using percussion methods, the annular space shall be at least 5 inches greater than the outside diameter of the well casing to a minimum depth of 25 feet.

(4) If the depth of casing is greater than 40 feet, the annular space below 40 feet may be filled with heavy drilling fluid taken from the borehole as long as the top 40 feet is properly grouted. In this case, the annular space below 40 feet shall be kept as small as possible to avoid settling.

b. Drilled wells in consolidated material.

(1) Minimum casing depth. Casing shall extend to a depth of at least 40 feet and be seated in firm rock. When the uppermost bedrock consists of creviced limestone or dolomite that does not produce water, the casing shall extend through the creviced formation, be seated in firm rock and be properly grouted.

(2) Grouting. For bedrock wells, full-length casing grouting is strongly recommended. Grout shall be placed to a minimum depth of 40 feet in accordance with 49.9(3),except when driving casing while percussion or casing-hammer/rotary drilling. When driving casing, #8 mesh bentonite or bentonite grout must be maintained around the outside of the casing. The bottom of driven casing must be equipped with a drive shoe. If a layer of low permeability material at least 5 feet thick is encountered less than 40 feet from the surface, the grout may be terminated at least 5 feet below the top of this low permeability material, but in no case less than 20 feet from the ground surface. Where local conditions warrant, the administrative authority may require more extensive grouting to protect the aquifer(s) that are penetrated.

(3) Annular space. The borehole shall be at least 3 inches greater than the outside diameter of the well casing for the upper 40 feet or the minimum grouting depth. When steel casing pipe is installed using percussion, or casing-hammer/rotary methods, the annular space shall be at least 5 inches greater than the outside diameter of the well casing to a minimum depth of 25 feet. When bedrock wells are full-length pressure-grouted through the casing, the 3-inch larger borehole is also only required for the top 25 feet.

(4) If the depth of casing is greater than 40 feet, the annular space below 40 feet may be filled with heavy drilling fluid taken from the borehole as long as the top 40 feet is properly grouted. In this case, the annular space below 40 feet shall be kept as small as possible to avoid settling.

(5) In fractured rock, where circulation of slurry cannot be maintained, grouting may be done with bentonite chips. The chips shall be hydrated with one gallon of water per bag of bentonite.

49.8(2) Bored and augered wells in unconsolidated materials. For bored or augered wells with concrete or clay tile casings at least 18 inches in diameter, buried-slab construction is required.

a. Casing. The concrete or vitrified clay pipe casing shall be terminated not less than 10 feet below ground surface and extend to a minimum of 20 feet. The casing shall be fitted with a reinforced concrete or steel plate into which a watertight steel or thermoplastic casing is firmly imbedded in or connected to a pipe cast or welded into the plate. This casing shall be at least 5 inches in diameter and shall extend from the plate to not less than 12 inches above established grade or the 100-year flood level, whichever is higher. A pitless adaptor shall be installed below frost depth on the newly installed plastic or steel casing.

b. Backfilling annular space. A 12-inch grout seal shall be poured over and around the plate. The annular space between the steel or thermoplastic casing and the borehole shall be backfilled with clean compacted soil free of debris or large organic material. During the backfilling process, the earth shall be thoroughly tamped to minimize settling. Grading around the well shall then be accomplished in accordance with subrule 49.7(2).

49.8(3) Driven and direct push wells. Sandpoint wells are typically constructed in sandy areas with a high water table. Groundwater in these areas is often susceptible to contamination. This type of construction is not recommended for potable water supply. Sandpoint wells shall meet the requirements of this chapter except for casing depth and grouting requirements.

49.8(4) Flowing artesian wells. Drilling operations shall extend into but not through the formation confining the water. The casing shall then be installed and the annular space full-length pressure-grouted and allowed to set. After setting, the drill hole shall then be extended into the confined water-bearing formation. Flow control from the well shall be provided by valved pipe connections or a receiving tank set at an altitude corresponding to that of the artesian head. Under no circumstances shall the water flow uncontrolled to waste. A direct connection between the discharge pipe and a receiving tank, sewer, or other source of contamination is prohibited.

567--49.9(455B) Material standards. All materials utilized in well water construction shall conform to the standards of the American Water Works Association (AWWA), the American Petroleum Institute (API), the American Society for Testing and Materials (ASTM), and the National Ground Water Association (NGWA) except as modified by these standards.

49.9(1) Water well casing.

a. Steel well casing and couplings.

(1) Steel well casing pipe shall have the dimensions and weights specified in Table 49.9(1)"a"(4). Well casing pipe shall be new steel pipe meeting one of the following standards:

(2) Each length of casing shall be legibly marked in accordance with API or ASTM marking specifications showing the manufacturer's or processor's name or trademark, size in inches, weight in pounds per foot, whether seamless or welded (type of weld) and the API or ASTM specification or trade monogram.

(3) All casing pipe joints shall be watertight welded construction or threaded couplings.

(4) Minimum casing pipe and coupling weights and dimensions are as follows:

b. Thermoplastic casing and couplings.

(1) Materials. Thermoplastic well casing pipe andcouplings shall be new polyvinyl chloride (PVC) oracrylonitrile-butadiene-styrene (ABS) material produced to and meeting the ASTM F 480 standard and shall have a standard dimension ratio (SDR) of 21, 17, or 13.5, a dimension ratio (DR) of 18 or 14, or a schedule 40 or 80 rating depending upon the specification. Styrene-rubber thermoplastic well casing pipe, including ASTM F 480, may not be used.

(2) Potable water standards. The thermoplastic well casing pipe, pipe couplings, cement, primer and other components used shall be approved for well casing pipe in potable water supplies by the NSF Standard Number 61 or the health effects portion of Standard Number 14 as they relate to well casing pipe, or an approved equivalent organization.

(3) Markings. Each length of casing shall be legibly marked showing the manufacturer's or processor's name or trademark, size in inches, and the ASTM F 480 specification or trade monogram.

(4) Casing joints. The thermoplastic pipe shall beassembled with either flush-threaded joints, integral-bell,solvent-cemented joints, one-piece solvent-cemented couplings or nonmetallic restrained joint system in a manner according to the specifications in ASTM F 480.

(5) Depths for plastic casing. The following table provides specifications for maximum depths (in feet of water head) to which PVC well casing of different strengths can be installed.

(6) When cement grout is used with thermoplastic casing, the manufacturer's specifications for use shall be followed except in the top 40 feet.

(7) Thermoplastic pipe extending above ground shall be protected from ultraviolet light exposure.

(8) Under no circumstances shall thermoplastic water well casing be driven.

49.9(2) Grouting guides. Casing that is to be grouted shall have a minimum of two sets of centering guides attached to the casing so as to permit the unobstructed flow and deposition of grout.

49.9(3) Grouting. Materials and procedures for grouting shall be as follows:

a. Concrete grout. The mixture, used with bored and augered wells, shall consist of cement, sand aggregate and water, in the proportion of one bag cement (94 lbs.) and an equal volume of aggregate to not more than six gallons of clean water. Concrete grout shall not be used below the water table. Admixtures to reduce permeability or control setting time must meet ASTM Standard C 494-92. Concrete grout may be used with permission of the administrative authority where large void spaces need to be filled.

b. Neat cement grout. The mixture shall consist of one bag of cement (94 lbs.) to not more than six gallons of clean water. Admixtures to reduce permeability or control setting time must meet ASTM Standard C 494-92.

c. Bentonite grout. A mixture of water and commercial sodium-bentonite clay manufactured for the purpose of water well grouting. Mixing shall be per manufacturer's specifications. Sodium-bentonite products that contain low solids, are designed for drilling purposes, or contain organic polymers shall not be used.

d. Exclusion. Drilling fluids and cuttings may not be used as grouting material for the minimum grouting depths.

If the excavation spanned is more than 2 feet, it must be filled with sand or compacted fill to provide a firm bed for the pipe. The first 12 inches of backfill over the pipe shall be applied in thin layers using material free from stones, boulders, large frozen chunks of earth or any similar material that would damage or break the pipe.

567--69.6(455B) Secondary treatment--subsurface absorption systems. Soil absorption systems are the best available treatment technology and shall always be used where possible.

69.6(1) General requirements.

a. Locations. All subsurface absorption systems shall be located on the property to maximize the vertical separation distance from the bottom of the absorption trench to the seasonal high groundwater level, bedrock, hardpan or other limiting layer, but under no circumstances shall this vertical separation be less than 3 feet.

b. Soil evaluation. A percolation test or professional soil analysis is required before any soil absorption system is installed.

(1) Percolation test. The percolation test procedure is outlined in Appendix B.

(2) Alternative analysis. If a professional soil analysis is performed, soil factors such as soil content, color, texture, and structure shall be used to determine a percolation rate.

(3) Acceptable percolation rate. An area is deemed suitable for conventional soil absorption if the average percolation test rate is 60 minutes per inch or less and greater than 1 minute per inch. However, if an alternative-type system is proposed (e.g., mound), then the percolation test should be extended to determine whether a percolation rate of 120 minutes per inch is achieved.

(4) Confining layer determination. An additional test hole 6 feet in depth or to rock, whichever occurs first, shall be provided in the center of the proposed absorption area to determine the location of groundwater, rock formations or other confining layers. This 6-foot test hole may be augered the same size as the percolation test holes or may be made with a soil probe.

c. Groundwater. If seasonal groundwater is present within 3 feet of the trench bottom final grade and cannot be successfully lowered by subsurface tile drainage, the area shall be classified as unsuitable for the installation of a standard subsurface absorption system. Consult the administrative authority for an acceptable alternative method of wastewater treatment.

d. Site limitations. In situations where specific location or site characteristics would appear to prohibit normal installation of a soil absorption system, design modifications may be approved by the administrative authority which could overcome such limitations. Examples of such modifications could be the installation of subsurface drainage, use of shallow or at-grade trenches, use of dual soil treatment areas, mound system or water conservation plans.

e. Prohibited drainage. Roof, foundation and storm drains shall not discharge into or upon subsurface absorption systems. Nothing shall enter the subsurface absorption system which does not first pass through the septic tank.

f. Prohibited construction. There shall be no construction of any kind, including driveways, covering the septic tank, distribution box or absorption field of an on-site wastewater treatment and disposal system. Vehicle access should be infrequent, primarily limited to vegetation maintenance.

g. Driveway crossings. Connecting lines under driveways shall be constructed of schedule 40 plastic pipe or equivalent, and shall be protected from freezing.

h. Easements. No wastewater shall be discharged upon any property under ownership different from the ownership of the property or lot upon which it originates unless easements to that effect are legally recorded and approved by the administrative authority.

69.6(2) Trench length requirements.

a. Percolation charts. Table IIIa specifies lineal feet of lateral trenches required in accordance with the results of the standard percolation tests. Tables IIIb and IIIc list optional methods for determining length of lateral trenches or sizing of absorption beds. The alternative option for increased rock usage (Table IIIb) shall be used only when the size of lots limits the use of trench lengths prescribed in Table IIIa. Absorption beds (Table IIIc) shall not be used except when the lot size limitations preclude the installation of a lateral trench system. Further details concerning limitations of these two alternatives should be obtained from the administrative authority prior to requesting authorization for installation.

b. Unsuitable absorption. Conventional subsurface soil absorption trenches shall not be installed in soils that have a percolation rate less than 1 minute per inch or greater than 60 minutes per inch. Plans for an alternative method of wastewater treatment shall be submitted to the administrative authority for approval prior to construction.

⁽²⁾For soils having more than 50 percent of very fine sand by weight, plus fine sand having a particle size range of 0.05 millimeters (sieve size 270) to 0.25 millimeters (sieve size 60), the 16-30 min. per inch values shall be used when gravelless pipe is installed.

69.6(3) Construction details. (All soil absorption trenches.)

a. Depth. Lateral trenches shall not exceed 36 inches in depth unless authorized by the administrative authority, but a more shallow trench bottom depth of 18 to 24 inches is recommended. Not less than 6 inches of porous soil shall be provided over the laterals. Minimum separation between trench bottom and groundwater, rock formation or other confining layers shall be 36 inches even if extra rock is used under the pipe.

b. Length. No lateral absorption trench shall be greater than 100 feet long.

c. Separation distance. At least 6 feet of undisturbed soil shall be left between each trench edge on level sites. The steeper the slope of the ground, the greater the separation distance should be. Two feet of separation distance should be added for each 5 percent increase in slope from level.

d. Grade. Trench bottom should be constructed level from end to end. On sloping ground, the trench shall follow a uniform land contour to maintain a minimum soil cover of 6 inches while ensuring a level trench bottom.

e. Compaction. There shall be minimum use or traffic of heavy equipment on the area proposed for soil absorption. In addition, it is prohibited to use heavy equipment on the bottom of the absorption area.

f. Fill soil. Soil absorption systems shall not be installed in fill soil. Disturbed soils which have stabilized for at least one year would require a recent percolation test.

g. Bearing strength. Soil absorption systems shall be designed to carry loadings to meet AASHTO H-10 standards.

h. Soil smearing. Soils with significant clay content should not be worked when wet. If soil moisture causes sidewall smearing, the trench bottom and sidewalls shall be scar-ified.

d. Pipe. Distribution pipe shall be PVC rigid plastic meeting ASTM Standard 2729, or other suitable material approved by the administrative authority. The inside diameter shall be not less than 4 inches, with perforations at least 1/2 inch and no more than 3/4 inch in diameter spaced no more than 40 inches apart. Two rows of perforations shall be provided located 120 degrees apart along the bottom half of the tubing (each 60 degrees up from the bottom centerline). The end of the pipe in each trench shall be sealed with a watertight cap unless, on a level site, a footer is installed connecting the trenches together. Coiled perforated plastic pipe shall not be used when installing absorption systems.

e. Gravel cover. Unbacked, rolled, 31/2-inch-thick fiberglass insulation, untreated building paper, synthetic drainage fabric, or other approved material shall be laid so as to separate the gravel from the soil backfill.

69.6(5) Gravelless pipe systems.

a. Application. Gravelless subsurface absorption systems may be used as an alternative to conventional 4-inch pipe placed in gravel-filled trenches. However, they cannot be used in areas where conventional systems would not be allowed due to poor permeability, high groundwater, or insufficient depth to bedrock.

b. Installation. Manufacturer's specifications and installation procedures shall be adhered to.

c. Material. The 8- and 10-inch I.D. corrugated polyethylene tubing used in gravelless systems shall meet the requirements of ASTM F667, Standard Specification for Large Diameter Corrugated Polyethylene Tubing.

d. Perforations. Two rows of perforations, 3/4 inch in diameter, shall be located 120 degrees apart along the bottom half of the tubing (each 60 degrees up from the bottom centerline). Perforations shall be cleanly cut into each inner corrugation along the length of the tubing and should be staggered so that there is only one hole in each corrugation.

e. Top marking. The tubing should be visibly marked to indicate the top of the pipe.

f. Filter wrap. All gravelless drainfield pipe shall be encased, at the point of manufacture, with a geotextile filter wrap specific to this purpose.

g. Trench width. If dug with a backhoe, the minimum trench width for the gravelless system shall be 18 inches in sandy loam soil to ensure proper backfill around the bottom half of the pipe. In clay soils, the minimum trench width shall be 24 inches. If the pipe is laid in with a wheel trencher leaving a curved trench bottom, the trench width may be just 2 inches wider than the outside diameter of the pipe.

h. Length of trench. The total length of absorption trench for a 10-inch gravelless tubing installation shall be the same as given in Table IIIa for a conventional absorption trench, except for fine sandy soils as noted in Table IIIa footnote. An increase of at least 20 percent in total trench length shall be required if 8-inch tubing is used rather than 10-inch.

69.6(6) Chamber systems.

a. Application. Chamber systems may be used as an alternative to conventional 4-inch pipe placed in gravel-filled trenches. However, they cannot be used in areas where conventional systems would not be allowed due to poor permeability, high groundwater, or insufficient depth to bedrock.

b. Installation. Manufacturer's specifications and installation procedures shall be closely adhered to.

c. Length of trench. The total length of absorption trench for chambers 24 inches or less in bottom width shall be the same as given in Table IIIa for a conventional absorption trench. For chambers 36 inches in width a reduction of 25 percent from the lengths given in Table IIIa may be used.

d. Sidewall. The chambers shall have at least 6 inches of sidewall slotted height.

69.6(7) Gravity distribution. Dosing is always recommended and preferred to improve distribution, improve treatment and extend the life of the system.

a. On a hillside, septic tank effluent may be serially loaded to the soil absorption trenches by drop boxes or overflow piping (rigid sewer pipe). Otherwise, effluent shall be distributed evenly to all trenches by use of a distribution box or commercial distribution regulator approved by the administrative authority.

b. Design. When a distribution box is used, it shall be of proper design and installed with separate watertight headers leading from the distribution box to each lateral.

c. Outlets height. The distribution box shall have outlets at the same level at least 4 inches above the bottom of the box to provide a minimum of 4 inches of water retention in the box.

d. Baffles. There shall be a pipe tee or baffle at the inlet to break the water flow.

e. Unused outlets. All unused outlet holes in the box shall be securely closed.

f. Interior coating. All distribution boxes shall be constructed of corrosion-resistant rigid plastic materials, or other corrosion-resistant material approved by the administrative authority.

g. Outlets level. All outlets of the distribution box shall be made level. A 4-inch cap with an offset hole approximately 21/2 inches in diameter shall be installed on each outlet pipe. These caps shall be rotated until all outlets discharge at the same elevation. Equivalent leveling devices may be approved by the local authority.

h. Equal length required. The soil absorption area serviced by each outlet of the distribution box shall be equal.

69.6(8) Dosing systems.

a. Pump systems.

(1) Pump and pit requirements. In the event the effluent from the septic tank outlet cannot be discharged by gravity and still maintain proper lateral depths, the effluent shall discharge into a watertight vented pump pit with an inside diameter of not less than 24 inches, equipped with a tight-fitting manhole cover at grade level. The sump vent shall extend a minimum of 6 inches above grade level and shall be a minimum size of 11/4 inches fitted with a return bend. The pump shall be of a submersible type of corrosion-resistant material.

(2) Pump setting. The pump shall be installed in the pump pit in a manner that ensures ease of service and protection from frost and settled sludge. The pump shall be set to provide a dosing frequency of approximately twice a day based on the maximum design flow. No on-site electrical connections shall be made in the pump pit. These connections shall be made in an exterior weatherproof box.

(3) Pressure line size. The pressure line from the pump to the point of discharge shall not be smaller than the outlet of the pump it serves.

(4) Drainage. Pressure lines shall be installed to provide total drainage between dosings to prevent freezing or be buried below frost level up to the distribution box.

(5) High water alarm. Pump pits shall be equipped with a sensor set to detect if the water level rises above the design high water level when the pump fails. This sensor shall activate an auditory or visual alarm to alert the homeowner that repairs are required.

(6) Discharge point. The effluent shall discharge under pressure into a distribution box or may be distributed by small diameter pipes throughout the entire absorption field.

b. Dosing siphons. Dosing siphons may also be used. Manufacturer's specifications shall be adhered to for installation. Similar dosing volumes and frequencies are recommended. Dosing siphons require periodic cleaning to ensure their continued proper operation.

567--69.7(455B) Mound system.

f. No soil under or up to 50 feet down gradient of the mound may be removed or disturbed except as specified herein.

g. Construction equipment which would cause undesirable compaction of the soil shall be kept off the base area. Construction or plowing shall not be initiated when the soil moisture content is high. If a sample of soil from approximately 9 inches below the surface can be easily rolled into a 1/8- to 1/4-inch diameter wire, the soil moisture content is too high for construction purposes.

h. Aboveground vegetation shall be closely cut and removed from the ground surface throughout the area to be utilized for the placement of the fill material.

i. The area shall be plowed to a depth of 7 to 8 inches, parallel to the land contour with the plow throwing the soil up slope to provide a proper interface between the fill and the natural soil. Tree stumps should be cut flush with the surface of the ground, and roots should not be pulled.

j. The base area of the mound is to be calculated on the results of percolation rate as indicated in Table IV. The base area of the mound below and downslope from the trenches, excluding the area under the end slopes, must be large enough for the natural soil to absorb the estimated daily wastewater flow.

(5) The outer ends of all pressure distribution lines shall be securely capped.

(6) The central pressure manifold should consist of 11/2-inch or 2-inch solid plastic pipe using a tee or cross for connecting the distribution lines.

n. Construction should be initiated immediately after preparation of the soil interface by placing all of the sandy fill material needed for the mound (to the top of the trench) to a minimum depth of 21 inches above the plowed surface. This depth will permit excavation of the trenches to accommodate the 9 inches of washed gravel or crushed stone necessary for the distribution piping.

o. The absorption trench or trenches shall be hand excavated to a depth of 9 inches, the bottoms of the trenches made certain to be level.

p. Twelve inches of gravel shall be placed in the trench and hand leveled, and then 3 inches of the gravel removed with a shovel in the location where the distribution pipe will be placed. After the distribution pipe is placed, the pipe shall be covered with 2 inches of gravel.

69.9(3) Subsurface sand filters.

a. Distribution system and cover.

(1) Gravel base. Six inches of gravel 3/4 inch to 21/2 inches in size shall be placed upon the sand in the bed.

(2) Distribution lines. Distribution lines shall be level and shall be horizontally spaced a maximum of 3 feet apart, center to center.

(3) Venting. Venting shall be placed on the downstream end of the distribution lines with each distribution line being vented or connected to a common vent. Vents shall extend at least 12 inches above the ground surface with the outlet screened, or provided with a perforated cap.

(4) Gravel cover. Enough gravel shall be carefully placed to cover the distributors.

(5) Separation layer. A layer of material such as unbacked, rolled 31/2-inch-thick fiberglass insulation, untreated building paper of 40- to 60-pound weight, synthetic drainage fabric or 4 to 6 inches of marsh hay or straw shall be placed upon the top of the upper layer of gravel.

(6) Soil cover. A minimum of 12 inches of soil backfill shall be provided over the beds.

(7) Distribution boxes. A distribution box shall be provided for each filter bed where gravity distribution is used. The distribution boxes shall be placed upon undisturbed earth outside the filter bed. Separate watertight lines shall be provided leading from the distribution boxes to each of the distributor lines in the beds.

b. Sizing of subsurface sand filters.

(1) Gravity flow.

1. For residential systems, single bed subsurface sand filters shall be sized at a rate of 240 square feet of surface area per bedroom.

2. Dual subsurface sand filters, constructed in series, shall be sized at the rate of 160 square feet of surface per bedroom in the first filter and 80 square feet of surface area per bedroom in the second filter in the series.

(2) Pressure dosed.

1. For residential systems, single bed subsurface sand filters dosed by a pump or dosing siphon may be sized at a rate of 180 square feet of surface area per bedroom.

1. 1.5 gallon/square feet/day for double bed sand filters.

2. 1.0 gallon/square feet/day for single bed sand filters.

3. Total surface area for any subsurface sand filter system shall not be less than 200 square feet.

69.9(4) Free access sand filters.

a. Description. Media characteristics and underdrain systems for free access filters are similar to those for subsurface filters. Dosing of the filter should provide for flooding the bed to a depth of approximately 2 inches. Dosing frequency is usually greater than two times per day. For coarser media (greater than 0.5mm) a dosing frequency greater than four times per day is desirable. Higher acceptable loadings on these filters as compared to subsurface filters relate primarily to the accessibility of the filter surface for maintenance. Gravel is not used on top of the sand media, and the distribution pipes are exposed above the surface.

b. Distribution. Distribution to the filter may be by means of troughs laid on the surface, pipelines discharging to splash plates located at the center or corners of the filter, or spray distributors. Care must be taken to ensure that lines discharging directly to the filter surface do not erode the sand surface. The use of curbs around the splash plates or large stones placed around the periphery of the plates will reduce the scour. A layer of washed pea gravel placed over the filter media may also be employed to avoid surface erosion. This practice will create maintenance difficulties, however, when it is time to rake or remove a portion of the media surface.

c. Covers. Free access filters may be covered to protect against severe weather conditions and to avoid encroachment of weeds or animals. The cover also serves to reduce odor conditions. Covers may be constructed of treated wooden planks, galvanized metal, or other suitable material. Screens or hardware cloth mounted on wooden frames may also serve to protect filter surfaces. Where weather conditions dictate, covers should be insulated. A space of 12 to 24 inches should be allowed between the insulated cover and sand surface. Free access filters may not be buried by soil or sod.

d. Loading. The hydraulic loading for free access sand filters should be from 2.0 to 5.0 gpd/sq.ft.

e. Number of filters. Dual filters each sized for the design flow are recommended for loading rates in excess of 31/2 gpd/sq.ft. treating septic tank effluent.

69.9(5) Dosing. Dosing for sand filters is strongly advised. Without dosing, the entire area of the sand filter is never effectively used. Dosing not only improves treatment effectiveness but also decreases the chance of premature failure.

a. Pumps. A pump shall be installed when adequate elevation is not available for the system to operate by gravity.

(1) The pump shall be of corrosion-resistant material.

(2) The pump shall be installed in a watertight pit.

(3) The dosing system shall be designed to flood the entire filter during the dosing cycle. A dosing frequency of greater than two times per day is recommended.

(4) A high water alarm shall be installed.

b. Dosing siphons. When a dosing siphon is used where elevations permit, such siphon shall be installed as follows:

(1) Dosing siphons shall be installed between the septic tank and the first filter bed.

(2) Dosing siphons shall be installed with strict adherence to the manufacturer's instructions.

c. Dosing tanks. The dosing tank shall be of such size that the siphon will flood the entire filter during the dosing cycle. A dosing frequency of greater than two times per day is recommended.

567--69.10(455B) Individual mechanical aerobic wastewater treatment systems. General requirements for individual mechanical aerobic wastewater treatment systems are as follows:

69.10(1) Use. Mechanical/aerobic systems shall be used when the administrative authority determines that the soil is unacceptable for a soil absorption system. Because of the higher maintenance requirements of mechanical/aerobic systems, preference should be given to sand filters, where conditions allow.

69.10(2) Certification. All individual mechanical aerobic wastewater treatment plants shall be certified by an ANSI-accredited third-party certifier to meet National Sanitation Foundation Standard 40, Class I, including appendices (May 1996).

69.10(3) Installation and operation. All individual mechanical aerobic wastewater treatment plants shall be installed, operated and maintained in accordance with the manufacturer's instructions and the requirements of the administrative authority. The aerobic plants shall have a minimum treatment capacity of 150 gallons per bedroom per day or 500 gallons, whichever is greater. Installation of these types of plants should be restricted to those locations where they can be monitored by the local administrative authority.

69.10(4) Effluent treatment. The effluent from individual mechanical aerobic wastewater treatment plants shall receive additional treatment through the use of intermittent sand filters, mound systems or subsurface absorption systems of a magnitude of half that prescribed in rules 69.6(455B), 69.7(455B) or 69.9(455B) or by discharge to a drip irrigation system as sized in 69.8(455B).

69.10(5) Maintenance contract. A maintenance contract with a manufacturer-certified technician shall be maintained at all times. Maintenance agreements and responsibility waivers shall be recorded with the county recorder and in the abstract of title for the premises on which mechanical aerobic treatment systems are installed. Mechanical aerobic units shall be inspected for proper operation at least three times a year.

69.10(6) Effluent sampling. Any open discharge from systems involving mechanical aeration shall have the effluent sampled at each inspection. In the spring, tests shall be run on all parameters as required in 69.9(1). At other times, only CBOD₅ testing is required.

567--69.11(455B) Constructed wetlands.

69.11(1) General site design.

a. Application. Constructed wetlands shall only be used where soil percolation rates at the site exceed 120 minutes per inch. Because of the higher maintenance requirements of constructed wetland systems, preference should be given to sand filters, where conditions allow.

b. Effluent treatment. The effluent from a constructed wetland shall receive additional treatment through the use of intermittent sand filters of a magnitude of half that prescribed in rule 69.9(455B).

c. Effluent sampling. Effluent sampling of constructed wetlands shall be performed twice a year or as directed by the administrative authority. In the spring, tests shall be run on all parameters as required in 69.9(1). At other times, only CBOD₅ testing is required.

69.11(2) Wetland design.

a. Depth. The wetland shall be of a subsurface flow construction with a rock depth of 18 inches and a liquid depth of 12 inches.

b. Materials. Substrate shall be washed river gravel with a diameter of 3/4 inch to 21/2 inches. If crushed quarried stone is used, it must meet the criteria listed in 69.6(4)"a."

c. Sizing and configuration. Detention time shall be a minimum of seven days.

(1) Dimensions. This may be accomplished with trenches 16 to 18 inches deep (12 inches of liquid), 3 feet wide with 100 feet of length per bedroom. This may also be done with beds 16 to 18 inches deep with at least 300 square feet of surface area per bedroom. The bottom of each trench or bed must be level within +/-1/2 inch.

(2) Configuration. Multiple trenches or beds in series should be used. Beds or trenches in series may be stepped down in elevation to fit a hillside application. If the system is on one elevation, it should still be divided into units by earthen berms at about 50 and 75 percent of the total length.

(3) Unit connections. Each subunit shall be connected to the next with an overflow pipe (rigid sewer pipe) that maintains the water level in the first section. Protection from freezing may be necessary.

d. Liner. Wetlands shall be lined with a synthetic PVC or PE plastic liner 20 to 30 mils thick.

e. Inlet pipe. Effluent shall enter the wetland by a 4-inch pipe sealed into the liner. With beds, a header pipe shall be installed along the inlet side to distribute the waste.

f. Protective berms. Wetland system sites shall be bermed to prevent surface water from entering the trenches or beds.

69.11(3) Vegetation.

a. Setting plants. Vegetation shall be established on the wetlands at time of construction. Twelve inches of rock is placed in each unit, the plants are set, then the final 4 to 6 inches of rock is placed.

b. Plant species. Only indigenous plant species shall be used, preferably collected within a 100-mile radius of the site. Multiple species in each system are recommended. Preferred species include, but are not limited to:

(1) Typha Latifolia - Common cattail

(2) Typha Angustifolia - Narrow leaf cattail

(3) Scirpus spp. - Bullrush

(4) Phragmites communis - Reed

c. Plant establishment. Transplantation is the recommended method of vegetation establishment. For transplanting, the propagule should be transplanted, at a minimum, on a 2-foot grid. The transplants should be fertilized, preferably with a controlled release fertilizer such as Osmocote 18-5-11 for fall and winter planting, 18-6-12 for spring planting, and 19-6-12 for summer planting. Trenches or beds should be filled with fresh water immediately.

d. Plant management. In the late fall the vegetation shall be mown and the detritus left on the wetland surface as a temperature mulch. In the early spring the mulch shall be removed and disposed of to allow for adequate bed aeration.

567--69.12(455B) Waste stabilization ponds.

69.12(1) General requirements. Waste stabilization ponds may be used if designed and constructed in accordance with the following criteria and provided the effluent is discharged in accordance with the requirements of the general NPDES permit listed in rule 69.2(455B).

c. Separation. The inlet and outlet should be separated to the maximum extent possible, ideally by a berm or baffle constructed in the lagoon to prevent short-circuiting.

69.12(6) Drainage. All surface water shall be diverted away from the waste stabilization pond.

69.12(7) Discharge.

a. Controlled discharge. If the pond is to be open discharged, it must be under controlled conditions. The effluent must be tested before discharge, and effluent quality must be less than CBOD of 25 mg/l and TSS of 25 mg/l. Another test must be taken during discharge with the same results. Pond discharge is permitted only in spring and fall when stream flows are highest.

b. Continuous discharge. If the pond is to have an unlimited continuous discharge, the effluent shall receive additional treatment through the use of intermittent sand filters, mound systems or subsurface absorption systems of a magnitude of half that prescribed in rules 69.6(455B), 69.7(455B) and 69.9(455B). Under continuous discharge, effluent sampling shall be as required for constructed wetlands as outlined in 69.11(1)"c."

69.12(8) Maintenance.

a. Fencing. All waste stabilization ponds are to be fenced adequately to prevent entrance of livestock and to discourage entrance by people into the area. Signs shall be posted warning of possible health and safety hazards.

(2) Percolation test holes shall be 4 to 12 inches in diameter and to the same depth as the proposed absorption trenches (not to exceed 36 inches in depth).

(3) Sides and bottoms of the test holes shall be scratched or roughened to provide a natural surface. All loose material shall be removed from each hole.

(4) The bottoms of the test holes shall be covered with approximately 2 inches of rock to protect the bottom from scouring action when the water is added.

(5) The hole shall be filled with at least 12 inches of clean water and this depth shall be maintained for at least 4 hours and preferably overnight if clay soils are present. It is important that the soil be allowed to soak for a sufficiently long period of time to allow the soil to swell if accurate results are to be obtained.

(6) In sandy soils with little or no clay, soaking is not necessary. If, after filling the hole twice with 12 inches of water, the water seeps completely away in less than 10 minutes, the test can proceed immediately.

(7) Except for sandy soils, percolation rate measurements should be made at least 4 hours but no more than 24 hours after the soaking period began. Any soil that sloughed into the hole during the soaking period is removed and the water level is adjusted to 6 inches above the gravel (or 8 inches above the bottom of the hole). At no time during the test is the water level allowed to rise more than 6 inches above the gravel.

(8) Immediately after adjustment, the water level is measured from a fixed reference point to the nearest 1/8 inch at 30-minute intervals. The test is continued until two successive water level drops do not vary by more than 1/8 inch. At least three measurements are made.

(9) After each measurement, the water level is readjusted to the 6-inch level. The last water level drop is used to calculate the percolation rate.

(10) In sandy soils or soils in which the first 6 inches of water added after the soaking period seeps away in lessthan 30 minutes, water level measurements are made at 10-minute intervals for a 1-hour period. The last water level drop is used to calculate percolation rate.

(11) The percolation rate is calculated for each test hole by dividing the time interval used between measurements by the magnitude of the last water level drop. This calculation results in a percolation rate in terms of minutes per inch. To determine the percolation rate for the area, the rates obtained from each hole are averaged. (If tests in the area vary by more than 20 minutes per inch, variations in soil type are indicated. Under these circumstances, percolation rates should not be averaged.) EXAMPLE: If the last measured drop in water level after 30 minutes is 5/8 inch, the percolation rate = (30 minutes)/(5/8 inch) = 48 minutes/inch.

ARC 7654A

Pursuant to the authority of Iowa Code section 455G.18, the Environmental Protection Commission gives Notice of Intended Action to amend Chapter 134, "Registration of Groundwater Professionals," Iowa Administrative Code.

The proposed amendments are intended to change the title of the chapter by removing "Registration" and replacing it with "Certification" and to remove the June 10, 1991, date requirement for meeting the five years of experience and training in order to initially qualify for certification. The requirement for having the five years of experience by June 10, 1991, was removed by 1997 Iowa Acts, Senate File 75.

Any interested person may make written suggestions or comments on these proposed amendments on or before December 9, 1997. Such written materials should be directed to Keith Bridson, Iowa Department of Natural Resources, Wallace State Office Building, 900 East Grand Avenue, Des Moines, Iowa 50319-0034, fax (515)281-7212, or E-mail at kbridso@max.state.ia.us.

There will be no public hearings on these proposed amendments.

These amendments may have an impact on small businesses as provided in Iowa Code section 17A.31.

These proposed amendments are intended to implement Iowa Code section 455G.18.

The following amendments are proposed.

ITEM 1. Amend the title to 567--Chapter 134 to read as follows:

f. Any person with five years of direct or related experience and training as a groundwater professional or in the field of earth sciences as of June 10, 1991. This must include a minimum of at least two years of education and training, and two years of experience as a groundwater professional.

ARC 7656A

Pursuant to the authority of Iowa Code section 249A.4 and 1997 Iowa Acts, Senate File 516, section 5, subsection 3, the Department of Human Services proposes to amend Chapter 40, "Application for Aid," Chapter 41, "Granting Assistance," and Chapter 75, "Conditions of Eligibility," appearing in the Iowa Administrative Code.

These amendments exempt all educational funds as income and as a resource when determining Family Investment Program (FIP) eligibility or benefit amount and Family Medical Assistance Program (FMAP)-related Medicaid coverage group eligibility.

Currently, the Department only exempts educational funds obtained from programs administered by the U.S. Secretary of Education but counts educational funds from other programs. When a client has a combination of exempt and also nonexempt educational funds, any allowable educational expenses the student may have are offset first against the educational income that is exempt. Any remaining expenses are then offset against the countable educational funds. As a result, even though the source of the educational funds in itself renders the funds exempt, by deducting educational expenses from these funds first, the exempt funds are, in fact, used in the eligibility and benefit determination. However, recent litigation in another program has raised an issue in the Family Investment Program and FMAP-related Medicaid Program. Amendments to the Higher Education Act of 1965 may prohibit the use of educational funds obtained from programs under the Secretary of Education in any calculation to determine FIP eligibility or benefit amount and FMAP-related Medicaid eligibility. The Department is proposing these amendments to eliminate any possibility of litigation or incorrect policy.

The Department has the option to still consider educational funds from programs other than those under the Secretary of Education to determine FIP eligibility and benefit amount and FMAP-related Medicaid eligibility. However, by eliminating the exempt educational funds from the eligibility and benefit calculation, little, if any, countable income will most likely remain. Determining countable educational income is a very complicated and error-prone process. Considering the very low number of FIP participants who are students with countable educational income, there seems to be little, if any, purpose in performing the required complex calculation. Also, better education will lead to better-paying jobs. Supporting clients' efforts at improving their marketable skills that will increase their opportunities for gainful employment is in line with the Department's philosophy on welfare reform.

Consideration will be given to all written data, views, and arguments thereto received by the Bureau of Policy Analysis, Department of Human Services, Hoover State Office Building, Des Moines, Iowa 50319-0114, on or before December 10, 1997.

These amendments are intended to implement Iowa Code section 249A.4 and 1997 Iowa Acts, Senate File 516, sections 3 and 8.

The following amendments are proposed.

ITEM 1. Amend subrule 40.27(1), paragraph "a," subparagraph (3), as follows:

(3) The assistance unit contains any member receiving nonexempt unearned income, the source or amount of which is expected to change more often than once annually, unless the income is from job insurance benefits, or interest oreducational income as described in 441--paragraph 41.27(1)"d"; or unless the assistance unit's adult members are 60 years old or older, or are receiving disability or blindness payments under Titles I, II, X, XIV, or XVI of the Social Security Act; or unless all adults, who would otherwise be members of the assistance unit, are receiving supplemental security income including state supplementary assistance.

ITEM 2. Amend rule 441--41.27(239) as follows:

Amend subrule 41.27(1) by rescinding and reserving paragraphs "d" and "e."

Amend subrule 41.27(6) by rescinding paragraph "r" and inserting the following new paragraph in lieu thereof:

r. All earned and unearned educational funds of an undergraduate or graduate student. Any extended social security benefits received by a parent or nonparental relative as defined at subrule 41.22(3), conditional to school attendance, shall be exempt.

Further amend subrule 41.27(6) by rescinding and reserving paragraph "s."

Amend subrule 41.27(9) by rescinding and reserving paragraph "g."

ITEM 3. Amend subrule 75.52(1), paragraph "a," subparagraph (3), as follows:

(3) The assistance unit contains any member receiving nonexempt unearned income, the source or amount of which is expected to change more often than once annually, unless the income is from job insurance benefits, or interest or educational income as described in paragraph 75.57(1)"b,"; or unless the assistance unit's adult members are 60 years old or older, or are receiving disability or blindness payments under Titles I, II, X, XIV, or XVI of the Social Security Act; or unless all adults, who would otherwise be members of the assistance unit, are receiving supplemental security income (SSI) including state supplementary assistance (SSA).

ITEM 4. Amend rule 441--75.57(249A) as follows:

Amend subrule 75.57(1) by rescinding and reserving paragraphs "b" and "c."

Amend subrule 75.57(6) by rescinding paragraph "r" and inserting the following new paragraph in lieu thereof:

r. All earned and unearned educational funds of an undergraduate or graduate student. Any extended social security benefits received by a parent or nonparental relative as defined at subrule 75.55(1), conditional to school attendance, shall be exempt.

Further amend subrule 75.57(6) by rescinding and reserving paragraph "s."

Amend subrule 75.57(9) by rescinding and reserving paragraph "g."

ARC 7657A

Pursuant to the authority of Iowa Code section 249A.4, the Department of Human Services proposes to amend Chapter 78, "Amount, Duration and Scope of Medical and Remedial Services," and Chapter 79, "Other Policies Relating to Providers of Medical and Remedial Care," appearing in the Iowa Administrative Code.

These amendments revise Medicaid reimbursement policies for chiropractors.

Under current policy Medicaid only pays chiropractors for manual manipulation of the spine. In 1997, the American Medical Association expanded the procedural code for chiropractors for manual manipulation of the spine from one to three codes, based on the area of the spine being manipulated. Medicare has predicted a 15 percent increase in chiropractic reimbursement with implementation of the new codes. These amendments adopt the new procedural codes.

In order to maintain budget neutrality, these amendments also restrict payment for manual manipulation of the spine to manipulations done for the purpose of correcting a subluxation demonstrated by X-ray which has resulted in a neuromusculoskeletal condition as defined below. Subluxation means an incomplete dislocation, off-centering, misalignment, fixation, or abnormal spacing of the vertebrae. No other diagnostic or therapeutic service furnished by a chiropractor is covered under the Medicaid program.

The subluxation must have resulted in a neuromusculo-skeletal condition for which chiropractic manipulative therapy (CMT) is appropriate treatment. The symptoms must be directly related to the subluxation that has been diagnosed. The mere statement or diagnosis of "pain" is not sufficient to support the medical necessity of CMT. CMT must have a direct therapeutic relationship to the patient's condition. The neuromusculoskeletal conditions generally require either short-term, moderate-term, or longer-term CMT depending on the category of the neuromusculoskeletal condition. If the CMT utilization guidelines are exceeded, documentation supporting the medical necessity of additional CMT must be submitted with the Medicaid claim form or the claim will be denied for failure to provide information.

The Iowa Chiropractic Society has been involved in the development of these rules.

Consideration will be given to all written data, views, and arguments thereto received by the Bureau of Policy Analysis, Department of Human Services, Hoover State Office Building, Des Moines, Iowa 50319-0114, on or before December 10, 1997.

These amendments are intended to implement Iowa Code section 249A.4.

The following amendments are proposed.

ITEM 1. Rescind rule 441--78.8(249A) and insert the following new rule in lieu thereof:

441--78.8(249A) Chiropractors.

78.8(1) Covered services. Chiropractic manipulative therapy (CMT) eligible for reimbursement is specifically limited by Medicaid to the manual manipulation (i.e., by use of the hands) of the spine for the purpose of correcting a subluxation demonstrated by X-ray. Subluxation means an incomplete dislocation, off-centering, misalignment, fixation, or abnormal spacing of the vertebrae.

78.8(2) Indications and limitations of coverage.

a. The subluxation must have resulted in a neuromusculoskeletal condition set forth in the table below for which CMT is appropriate treatment. The symptoms must be directly related to the subluxation that has been diagnosed. The mere statement or diagnosis of "pain" is not sufficient to support the medical necessity of CMT. CMT must have a direct therapeutic relationship to the patient's condition. No other diagnostic or therapeutic service furnished by a chiropractor is covered under the Medicaid program.

b. The neuromusculoskeletal conditions listed in the table in paragraph "a" generally requires either short-,moderate-, or long-term CMT. A diagnosis or combination of diagnoses within Category I generally requires short-term CMT of 12 per 12-month period. A diagnosis or combination of diagnoses within Category II generally requiresmoderate-term CMT of 18 per 12-month period. A diagnosis or combination of diagnoses within Category III generally requires long-term CMT of 24 per 12-month period. For diagnostic combinations between categories, 28 CMTs are generally required per 12-month period. If the CMT utilization guidelines are exceeded, documentation supporting the medical necessity of additional CMT must be submitted with the Medicaid claim form or the claim will be denied for failure to provide information.

c. CMT is not a covered benefit when:

(1) The maximum therapeutic benefit has been achieved for a given condition.

(2) There is not a reasonable expectation that the continuation of CMT would result in improvement of the patient's condition.

(3) The CMT seeks to prevent disease, promote health and prolong and enhance the quality of life.

78.8(3) Documenting X-ray. An X-ray must document the primary regions of subluxation being treated by CMT. CMT of additional regions of subluxation without a documenting X-ray will be allowed only if the additional regions of subluxation are reasonably related to the primary regions of subluxation. The clinical records must clearly document the relationship of the additional regions of subluxation to the primary regions of subluxation.

The documenting X-ray must be taken at a time reasonably proximate to the initiation of CMT. An X-ray is considered to be reasonably proximate if it was taken no more than 12 months prior to or 3 months following the initiation of CMT. X-rays need not be repeated unless there is a new condition. No X-ray is required for pregnant women and children aged 18 and under.

The X-ray films shall be labeled with the patient's name and date the X-rays were taken and shall be marked right or left. The X-ray shall be made available to the department or its duly authorized representative when requested. A written and dated X-ray report, including interpretation and diagnosis, shall be present in the patient's clinical record.

This rule is intended to implement Iowa Code section 249A.4.

ITEM 2. Rescind 347--Chapter 42 and adopt new 875--Chapter 201 in lieu thereof:

201.1(1) General. All boilers and pressure vessels covered by Iowa Code chapter 89 shall be inspected by a division inspector or special inspector within a 60-day period prior to the expiration date of an operating certificate. Modification of this period will be permitted only upon written application showing just cause for waiver of the 60-day period. Special inspections may be conducted at any time mutually agreed to by the division and the object's owner or user.

201.1(2) Inspections conducted by special inspectors. Special inspectors shall leave a copy of the completed report with the insured at the time of the inspection and shall submit reports to the division within 30 days of the inspection. The reports shall list all adverse conditions and requirements, if any. If the special inspector has not notified the division of the inspection results within 30 days of the expiration of an operating certificate, the division may conduct the inspection. If the division inspects a boiler or pressure vessel due to the failure of a special inspector to notify the division of the inspection results, the specified fees in subrule 200.4(3), paragraph "m," shall be paid by the insurance company which employs the special inspector.

201.1(3) Type of inspection. The inspection shall be an internal inspection when required; otherwise, it shall be as complete an external inspection as possible. An internal inspection of an unfired steam pressure vessel operating in excess of 15 pounds per square inch may be required by the commissioner when an inspector observes any deviation from these rules, Iowa Code chapter 89, or the construction or installation code, the National Board Inspection Code. Conditions including, but not limited to, the following may also be the basis for an internal inspection:

1. Visible metal or insulation discoloration due to excessive heat.

2. Visible distortion of any part of the pressure vessel.

3. Visible leakage from any pressure-containing boundary.

4. Any operating records or verbal reports of a vessel being subjected to pressure above the nameplate rating or temperature above or below the nameplate design temperature.

5. A suspected or known history of internal corrosion or erosion.

6. Evidence or knowledge of a vessel having been subjected to external heat from a resulting fire.

7. A welded repair not documented as required.

8. Personal injury, property damage accident, or malfunction affecting the pressure vessel's integrity.

875--201.2(89) Certificate. A certificate to operate shall not be issued until the boiler or pressure vessel complies with the applicable rules and all fees have been paid.

875--201.3(89) Preinspection owner or user preparation.

201.3(1) Preparation of objects. Each owner or user shall ensure that each object covered by Iowa Code chapter 89 is prepared for inspection pursuant to this rule.

201.3(2) Permit-required confined spaces (29 CFR 1910.146 in effect on July 1, 1997) and control of hazardous energy (lock-out/tag-out) (29 CFR 1910.147 in effect on July 1, 1997) compliance.

a. It is the responsibility of the owner or user to assess all objects for compliance with the confined space and lock-out/tag-out standards. If an object is a non-permit-required confined space or a permit-required confined space as defined by 29 CFR 1910.146, the owner or user must comply with all the requirements of 29 CFR 1910.146 and 1910.147 in preparing the object for inspection.

b. It is the duty of the owner or user to inform any inspector of the owner's or user's confined space policy and standards, supply to the inspector all information necessary to assess whether the confined space is safe for entry, and ensure all inspectors comply with the policy and Iowa occupational safety and health standards for confined space entry.

c. If the requirements of 29 CFR 1910.146 and 1910.147 are not met, the inspector shall not enter the space or, if there is a breach of the policy or standard, the inspection process shall cease until the space is reassessed and determined to be safe. It is the right of an inspector to verify any of the information supplied. No inspector shall violate the owner's or user's confined space or lock-out/tag-out policies in making an inspection.

d. The owner or user shall have all objects locked-out or tagged-out prior to entry for inspection or testing.

201.3(3) Hydrostatic tests. The owner or user shall prepare for and apply a hydrostatic test, whenever necessary, on the date specified by the division's inspector, which date shall be not less than seven days after the date of notification.

201.3(4) Boilers. A boiler shall be prepared for internal inspection in the following manner:

a. Water shall be drawn off and the boiler washed thoroughly.

b. Manhole and handhole plates, washout plugs and inspection plugs in water columns shall be removed as required by the inspector. The furnace and combustion chambers shall be thoroughly cooled and cleaned.

c. All grates of internally fired boilers shall be removed.

d. Brickwork shall be removed as required by the inspector in order to determine the condition of the boiler, header, furnace, supports or other parts.

e. If it is found that steam or hot water is leaking into a boiler or unfired pressure vessel when opened for inspection, the source of the leakage shall be disconnected, if necessary, to eliminate the steam or hot water from the boiler or pressure vessel to be inspected.

f. Before opening the manhole or handhole plates and entering any parts of the steam-generating unit connected to the common header with other boilers, the nonreturn and steam stop valves must be closed, tagged, and locked. Drain valves between the two valves must be opened. Blowoff lines, where practicable, shall be disconnected between pressure parts and valves. All drains and vent lines shall be opened.

g. Low water fuel cutoff controls shall be opened or removed to allow for visual inspection.

201.3(5) Pressure vessels. The extent of inspection preparation for a pressure vessel will vary. If the inspection is to be external only, advance preparation is not required other than to afford reasonable access to the vessel. For combined internal and external inspections of small vessels of simple construction handling air, steam, nontoxic or nonexplosive gases or vapors, minor preparation is required including isolating the vessel from its source of pressure, affording reasonable means of access and removing manhole plates and inspection opening closures. In other cases, preparation shall include draining, venting and purging the vessel to free toxic, explosive or other harmful gases or vapors, providing suitable safeguards to prevent leakage or accidental inflow of harmful substances into the vessel, removing manhole plates and inspection opening closures, cooling and cleaning the interior of the vessel and removing the internal fittings and appurtenances to permit satisfactory inspection of the interior of the vessel.

201.3(6) Removal of covering or brickwork to permit inspection. If the object is jacketed so that the longitudinal seams of shells, drums, or domes cannot be seen, sufficient jacketing, setting wall, or other form of casing or housing shall be removed to permit reasonable inspection of the seams and so that the size of rivets, pitch of the rivets, and other data necessary to determine the safety of the object may be obtained, providing the information cannot be determined by other means. Brickwork shall be removed as required by the inspector in order to determine the condition of the boiler, header, furnace, supports or other parts.

201.3(7) Improper preparation for inspection. If an object has not been properly prepared for an internal inspection, or if the owner or user fails to comply with the requirements for hydrostatic tests as set forth in this chapter, the inspector may decline to make the inspection or test, and the inspection certificate shall be withheld until the owner or user complies with the requirements.

These rules are intended to implement Iowa Code chapter 89 and 1997 Iowa Acts, House File 399.

ITEM 3. Adopt new 875--Chapter 202 as follows:

875--202.2(89) Denials. The labor commissioner may refuse to issue or renew a special inspector's commission for failure to complete an application package or for any reason listed in rules 202.4(89) to 202.6(89).

875--202.3(89) Investigations. Investigations shall take place at the time and in the places the labor commissioner directs. The labor commissioner may investigate for any reasonable cause. The labor commissioner may conduct interviews and utilize other reasonable investigatory techniques. Investigations may be conducted without prior notice.

875--202.4(89) Reasons for probation. The labor commissioner may issue a notice of commission probation where an investigation reasonably reveals the special inspector filed inaccurate reports.

ARC 7668A

Pursuant to the authority of Iowa Code sections 455G.4(3), 455G.6(15), 455G.9 and 455G.21, the Iowa Comprehensive Petroleum Underground Storage Tank Fund Board (Board) proposes to amend Chapter 11, "Remedial or Insurance Claims," Iowa Administrative Code.

The rules in Chapter 11 describe the guidelines for reimbursement of remedial and insurance claims.

Paragraph 11.1(3)"b" requires that any owner or operator applying for remedial benefits shall demonstrate financial responsibility coverage no later than October 26, 1990. If there is a lapse in financial responsibility coverage for any period after October 26, 1990, the owner/operator will no longer be eligible for benefits if the site for which benefits are being requested has active tanks during the time the owner was unable to demonstrate financial responsibility. This paragraph requires that all owners maintain financial responsibility continuously while tanks are operational. As a result of this paragraph, those owners who made a good-faith attempt to maintain their financial responsibility coverage through the state insurance fund, but encountered a lapse of coverage due to improper documentation, incorrect premium payment or missing a deadline, lost not only their financial responsibility coverage but also all remedial benefits to address past contamination.

Prior to 1996, owners whose coverage lapsed were able to purchase backdated insurance if they could document compliance with underwriting criteria and all payments were made. However, under current Board rules, backdating insurance is no longer allowed except for innocent landowner claims for periods prior to December 1993. Therefore, a lapse of coverage for even a very short period of time will result in a loss of all remedial benefits.

This proposed amendment will allow for the reinstatement of remedial benefits if the lapse in financial responsibility coverage occurred after an owner/operator made a good-faith attempt to comply with the coverage requirements. Although coverage will not be backdated, the owner/operator will remain eligible for remedial benefits if extenuating circumstances are documented which created the lapse in coverage and the owner can document good-faith attempts to maintain that coverage.

Any interested person may make written suggestions or comments on this proposed amendment on or before December 9, 1997.

The following amendment is proposed.

Amend paragraph 11.1(3)"b" as follows:

b. To be eligible for benefits under Iowa Code section sections 455G.9 and 455G.21, any owner or operator applying for such benefits shall demonstrate financial responsibility coverage using a method provided for under 567--Chapter 136 no later than October 26, 1990. If an owner or operator is unable to demonstrate financial responsibility coverage, or there is a lapse in the financial responsibility coverage for any period after October 26, 1990, the owner/operator will no longer be eligible for benefits if the site for which benefits are being requested has active tanks during the time the owner/operator was unable to demonstrate financial responsibility or if there is a lapse of financial responsibility coverage. The financial responsibility coverage requirement shall not be required on tanks which are temporarily closed consistent with 11.1(3)"o." subject to the following limitations:

(1) The financial responsibility coverage requirement shall not be required on tanks which are temporarily closed consistent with 11.1(3)"o."

(2) A lapse of financial responsibility coverage shall not cause loss of remedial benefits if the owner or operator can demonstrate:

1. Good-faith attempts were made to maintain the financial responsibility coverage;

2. Communications were ongoing between the owner or operator and the board in an attempt to maintain financial responsibility coverage at the time of the lapse;

3. The lapse in coverage was due to failure to timely submit proper documentation, failure to timely pay full payment of required premium, or both;

4. If the lapse was due to a failure to timely submit proper documentation:

* The owner or operator is able to demonstrate that documentation was submitted in a good-faith attempt to comply with the financial responsibility criteria.

* The owner or operator can provide factual support that the documentation submitted was sufficient to maintain financial responsibility coverage.

* The owner or operator submits a signed affidavit certifying that the owner or operator believed the documentation submitted was sufficient to maintain financial responsibility coverage.

5. If the lapse was due to a failure to timely submit full payment of required premium:

* The owner or operator is able to demonstrate that the payment was submitted in a good-faith attempt to comply with the financial responsibility criteria.

* The owner or operator can provide factual support that the payment submitted was sufficient to maintain financial responsibility coverage.

* The owner or operator submits a signed affidavit certifying that the owner or operator believed the payment submitted was sufficient to maintain financial responsibility coverage.

6. The owner or operator submits an amount equal to the full premium and any applicable surcharges that would have been required if financial responsibility coverage had been maintained.

The board will determine if the action taken by the owner or operator qualifies as good faith based upon the financial responsibility coverage requirements and the owner or operator's knowledge of and experience with financial responsibility coverage requirements and general business principles. When determining good faith, the board may consider the owner or operator's past history of maintaining financial responsibility coverage, the extent of the owner or operator's business knowledge taking into consideration business size and the number of UST sites owned or operated, compliance with other environmental programs, and other events occurring at the time of the financial responsibility coverage lapse which may have impacted the owner or operator's actions when attempting to maintain the financial responsibility coverage.
