- A Triple Bottom Line Assessment of Traditional and Green Infrastructure Options for Controlling CSO Events in Philadelphia's Watersheds
The Philadelphia Water Department conducted a triple botttom line (TBL) study as a component of options analyses for controlling combined sewer overflows (CSOs). The options include combinations of traditional infrastructure and green infrastructure approaches. The key finding of the TBL assessment is that green infrastructure approaches provide a wide array of important environmental and social benefits to the community that are not typically provided by traditional infrastructure approaches.

- 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).

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.

- Water Quality Scorecard
EPA's Water Quality Scorecard was developed to help local governments identify opportunities to remove barriers, and revise and create codes, ordinances and incentives for better water quality protection. It guides municipal staff through a review of relevant local codes and ordinances, across multiple municipal departments and at the three scales within the jurisdiction of a local government (municipality, neighborhood, and site), to ensure that these codes work together to protect water quality goals. The two main goals of this tool are to: (1) help communities protect water quality by identifying ways to reduce the amount of stormwater flows in a community and (2) educate stakeholders on the wide range of policies and regulations that have water quality implications.
The scorecard is intended for municipalities of various sizes in rural, suburban and urban settings, including those that have combined sewers, municipal separate storm sewers and those with limited or no existing stormwater infrastructure. It can help municipal staff, stormwater managers, planners, and other stakeholders better understand where a municipality's land development regulations and other ordinances may present barriers or opportunities to implementing a comprehensive water quality protection approach. The scorecard provides policy options, resources and case studies to help communities develop a comprehensive water quality program.
