October, 2013 The Honorable Gina McCarthy, Administrator U.S. Environmental Protection Agency Ariel Rios Building, 1200 Pennsylvania Ave. NW Washington, DC 20460 Re: Please Act Now to Protect Clean Water Dear Administrator McCarthy: We write to express our strong support for two actions EPA can take to help make our nation’s water resources safe and clean. Please modernize the national stormwater regulations and use your existing authority to ensure that sites contributing to current water quality problems are controlled. EPA can reduce pollution and flooding while creating new, green economy jobs and business opportunities for companies and organizations like ours. As operators of small businesses and associations that design, manufacture, install, and maintain green roofs, we understand the benefits that both an updated set of stormwater regulations and a requirement to reduce uncontrolled discharges from already built areas in our communities will provide. As we have realized through numerous projects around the country, these benefits are environmental and economic in nature. Enacting modernized, consistent stormwater standards will lead to more widespread use of our effective and affordable practices, greening our communities while minimizing the harmful impacts of runoff. In areas where similar standards already exist, our businesses have helped property owners, developers, and communities meet water quality goals while contributing to economic growth. With nationwide standards, collectively, our professions will be able to create more jobs for local residents in designing, building, installing and maintaining these controls. This is an opportunity to demonstrate how improved regulations can drive innovation and investment in stormwater infrastructure, creating both economic growth and healthier waters. We understand that EPA is developing rules that will require new and redeveloped sources of stormwater to be designed to retain the vast majority of runoff that would otherwise occur. Such safeguards would be an enormous step forward to achieving water quality and economic goals. But addressing new and redeveloped areas alone will not clean up already-polluted waterways. That’s why we also support the recent initiative insisting that EPA require certain stormwater sources in polluted watersheds to obtain pollution-limiting permits. These petitions present an important opportunity to reduce the currently uncontrolled, permanent discharges from already built areas in our communities, discharges which if left unabated will continue to undermine environmental health and economic prosperity. These complementary efforts will not only help restore our water bodies and provide new business opportunities. Requiring stormwater dischargers to retain runoff on-site will also help municipalities required to control urban pollution to meet their clean water obligations by ensuring that responsibility for runoff pollution is shared between the public and private sectors. We appreciate EPA’s efforts to promote cost-effective, job-creating responses to stormwater challenges and look forward to contributing further to this important effort. Sincerely,
