Which of the following best describes the institution’s approach to rainwater management?:
Comprehensive policies, plans or guidelines that require LID practices for all new projects

A brief description of the institution’s green infrastructure and LID practices:

Saint Mary’s has incorporated control measures similar to the “Minimum Control Measures” identified by the U.S. EPA for Phase II MS4 NPDES permitees. Though Saint Mary’s is not subject to the MS4 Phase II requirements, U.S. EPA’s Minimum Control Measures have provided guidance to Saint Mary’s as it developed its own “Control Measures,” listed below:
• College Community Education and Outreach on Stormwater Impacts
• College Community Involvement / Participation
• Non-Stormwater Discharge Detection and Elimination
• Pollution Prevention / Good Housekeeping for Facilities Operation and Maintenance
• Construction and Post-construction Site Stormwater Runoff Control

Saint Mary’s goal in developing these control measures is to reduce the discharge of pollutants to the extent feasible, considering technological availability and economic practicability and achievability, and to identify activities or structural improvements that help reduce the quantity and improve the quality of the stormwater runoff. The best management practices (BMPs) that have been included were selected by Saint Mary’s to achieve this reduction in pollutant discharge to the storm drain system. BMPs include treatment controls, operating procedures, and practices to control site runoff, spills and leaks, sludge or waste disposal, or drainage from raw material storage. BMPs will be updated as appropriate to conform to emerging best practices and actual experience

A brief description of the institution’s rainwater management policy, plan, and/or guidelines that supports the responses above:

Saint Mary’s College has developed a Stormwater Pollution Prevention Plan (“SWPPP”) in order to implement its commitment to reduce the chances of pollutants from entering into the storm drain system from its campus to the extent feasible, considering technological availability and economic practicability and achievability, and consistent with measures being implemented by other similarly-situated academic institutions. Though Saint Mary’s does not fall under Non-traditional MS4 regulations, it has drawn from those regulations and related guidelines and best practices in the developed of this SWPPP. This SWPPP identifies the potential on-campus sources of pollutants that might affect the quality of stormwater discharges and provides best practices in order to reduce non-stormwater discharges in the storm drain system.
