Statement from CBF on EPA Stormwater Modeling Data
(RICHMOND, VA)— Mike Rolband of WSSI and others have expressed concern about the Environmental Protection Agency's (EPA) estimates of impervious surface changes over time in the Bay watershed. The Chesapeake Bay Foundation (CBF) appreciates being provided an opportunity to review his findings and work with Mr. Rolband and EPA over the past two months to address his concerns. In response, Ann Jennings, CBF Virginia Executive Director, issued the following statement:
"Since impervious surface is a key input for calculating urban pollution loads in the Bay model, it is essential that the EPA model provide reasonable and defensible estimates. It is our understanding that EPA has already committed to take steps over the next month to acquire the necessary information to ensure that the model output best reflects reality.
"However, one does not need a model to see the impact of development. Think back over the last 20 years, and we all have seen suburban sprawl, strip malls, and other development sprouting up from farm fields and forest land. There is no dispute that pollution caused by development has damaged local waterways.
"It is essential that the McDonnell Administration engage the conservation and building communities and move forward with adequate regulations based on sound science that will allow new development to continue without adding more insult to our already polluted waterways."
