• Municipal Separate Storm Sewer System (MS4) Program Evaluation Guidance

The MS4 Evaluation Guide is primarily for use by NPDES authorities to evaluate the quality of Phase I and Phase II MS4 programs, for permit compliance, technical assistance, and other purposes. It can be used for comprehensive program evaluations, or for certain components. It can also be used by MS4 program managers to evaluate their own programs.

EPA encourages state NPDES stormwater programs to adapt this Guide to their state programs. It is being provided in Word so that programs can incorporate state-specific program components into the Guide, and have a single manual for inspectors and others to use. EPA welcomes feed-back on the Guide based on experiences of state and regional evaluations. As state and EPA NPDES programs conduct more MS4 program evaluations we will undoubtedly learn a number of lessons about program evaluations. We are committed to making timely updates to the guide as the MS4 program evolves (EPA-833-R-07-003).

• Policy on Using the Clean Water State Revolving Fund to Finance Section 320 Comprehensive Conservation and Management Plan Projects (PDF) (219KB)

CAFOs and stormwater programs that have been issued Phase I or Phase II stormwater permits can not be defined as nonpoint source pollution and can not receive funding as a nonpoint source project. This memorandum clarifies that they are eligible for funding if the project is included in the state's approved National Estuary Program's Comprehensive Conservation and Management Plan (CCMP). Section 320 for CCMPs addresses estuary problems, and the Clean Water State Revolving Fund may be used to fund any or all of the projects identified in the plans to correct estuary problems. Examples of types of projects include wetlands purchase, septic system upgrades, stormwater system enhancements, and agricultural waste management systems, including manure containment ponds, loading, spreading, and injection equipment.

A letter was sent to the EPA Regions and state permitting authorities to encourage the further use of this provision. This document includes a sample letter and attachment that was sent to EPA Region 1 and the state of Alabama.
