567—91.2 (455B) Scope of title. The department has jurisdiction over the surface water and groundwater of the state to prevent, abate and control pollution. As part of that general responsibility, the department and the Iowa finance authority are jointly designated to conduct the administration of the CWSRF loan assistance program to assist in the financing of infrastructure projects pursuant to the Clean Water Act. A project must comply with this chapter and 567—Chapter 92 or 567—Chapter 93 to be eligible for a CWSRF loan. This chapter provides the rating criteria to be used to rank eligible projects for funding. Rating criteria are provided for point source projects and nonpoint source projects. The nonpoint source projects are divided into three activities:
	  1. 	 Livestock water quality facilities;
	  2. 	 Local water protection projects; and
	  3. 	 General nonpoint source projects.
Rating criteria for onsite wastewater systems are not included at this time because the loan assistance is based on a first-come, first-funded concept.
