New developments would have to meet more stringent stormwater-retention standards than redeveloped sites under a forthcoming Environmental Protection Agency proposal, said Christopher Kloss, the agency's green-infrastructure and stormwater coordinator. The more relaxed standards for redeveloped sites reflect the EPA's desire to encourage businesses to invest in urban redevelopment projects, Kloss said. An "unequal playing field" results from having stormwater standards in municipal separate storm sewer systems "and not outside," he said.
The Environmental Protection Agency says it will drop the numeric limit it set for stormwater runoff at construction sites. That move helps settle a lawsuit filed by the National Association of Home Builders, Utility Water Act Group, and Wisconsin Builders Association. "The proposed numeric limits were a 'one-size-fits-nowhere' approach that would have cost a fortune to implement and would not have improved water quality," said Jerry Deschane, WBA executive vice president.
Philadelphia's $2B plan to build a sustainable stormwater-management system has been approved by the Environmental Protection Agency. The green infrastructure plan includes installing porous pavement, roadside plantings and green roofs to collect rainwater runoff. "The city has earned a place as a national and global leader on sustainable innovation and clean water protection," said EPA Administrator Lisa Jackson.
A new construction-site rule issued by the Environmental Protection Agency will establish minimum national standards aimed at minimizing sediment discharges from such sites and improve water quality across the U.S. The rule, which will be implemented in phases over four years, will require construction-site owners to use best management practices to prevent water pollution and to comply with federal regulations on stormwater discharges.
The EPA has issued a plan to reduce stormwater runoff and sewer overflows. The strategy, put together with state and national partners, considers options including green roofs, trees and tree boxes and other green infrastructure solutions that can also help improve air quality and reduce urban island heat.
