Program Findings Conclusions Proposed 20 Year CSO Plan meets Regulatory Criteria for CSO Control >85% CSO Volume Reduction System-wide. >95% Water Quality Attainment. CSO Plan Programmed over 20 years, Non-CSO Programmed over 40 years. RI at 2% in <20 years. CSO and Non-CSO components provide SWSC renewal to critical infrastructure and enhanced CSO control while reducing risk. KLEINFELDER CONFIDENTIAL The Stormwater Nexus CSO communities have taken the lead on Integrated Planning efforts due to heavy cost burden of wet weather solutions (e.g. sewer separation) NJPDES Stormwater Permits, TMDL pollutant reduction goals and non-point source (stormwater) mitigation are becoming a significant potential competitor for limited budget resources KLEINFELDER CONFIDENTIAL Re-Calibrating The Cost of Stormwater Compliance September 2011Final Report:
Sustainable Stormwater Funding Evaluation for the Upper Charles River Communities of Bellingham, Franklin and Milford, MA. KLEINFELDER CONFIDENTIAL Escalating Costs Capital and Operating Estimated between $30M - $75M in capital costs to meet phosphorus load reductions required in TMDL KLEINFELDER CONFIDENTIAL Conundrums and Contradictions CSO Program Strategies vs. MS4 Regulations (Economic Reality 101) Sewer Separation predominant approach for CSO mitigation TMDL studies/allocations on the basis of existing conditions New separated flows equal to New or Additional Discharges subject to antidegradation requirements KLEINFELDER CONFIDENTIAL
KLEINFELDER CONFIDENTIAL The Hand-off Existing Stormwater Criteria Additional Stormwater Criteria Remove Remove first 1 of Infiltration/Inflow rainfall Mitigate 25 year storm Recharge 40% of peak discharge to 2 runoff volume year Remove 100% total 80% TSS removal phosphorous load
KLEINFELDER CONFIDENTIAL Intersection at Green Infrastructure Benefits of GI/LID Peak flow reduction (CSO and SW benefit) Pollutant load reduction (CSO and SW benefit) Groundwater recharge base flow maintenance Community aesthetic/recreational value Greater adaptive capacity than piped systems (CSO and SW benefit) KLEINFELDER CONFIDENTIAL The Challenge EPA guidance is clear on outputs and outcomes, but is not well developed regarding process: When developing an integrated plan, a municipality/community must determine and define the scope of the integration effort, ensure the participation of entities that are needed to implement the integrated plan, and identify the role each entity will have in implementing the plan. KLEINFELDER CONFIDENTIAL The Challenge CSO and MS4 programs involve a high degree of technical and regulatory complexity. Scoping can be challenging. The CSO permit holder for a geographic area may not be the MS4 permit holder in that jurisdiction. Collaboration can be challenging.
Multiple stakeholders with different backgrounds can have widely different notions of the problems and solutions, creating social complexity and the potential for controversy.

Integrate state-of-the-art risk management process into CSO programs to consistently produce positive outcomes despite the technical and social complexities involved. What is Risk? The effect of uncertainty on objectives Involves both hazard and opportunity Objectively measured by probability, magnitude, and controls Perception is subjectively influenced by perspective What is Risk Management? Robust process for identifying and analyzing hazards and opportunities, and Consistent, explicit system of controls to optimize resource allocation. KLEINFELDER CONFIDENTIAL Risk Management Benefits Encourage proactive, collaborative management to identify opportunities and threats. Establish a consistent and transparent basis for decision making and planning Tailored to organizational need Uniform and explicit risk appetite Program and processes for monitoring,
