EPA proposes updated general permit for stormwater discharges from industrial activities

WASHINGTON, D.C. — The U.S. Environmental Protection Agency (EPA) is proposing an updated draft permit to regulate stormwater discharges from industrial activities to replace the current 2008 Multi-Sector General Permit (MSGP) when it expires later this year. The proposed permit will help protect our nation's waterways from industrial sector pollutants, which can contribute to aquatic ecosystem degradation, increase drinking water treatment costs, and impair the recreational use and aesthetic value of waterways. 

SWEMA provides stormwater BMP Maintenance Ordinance template

ST. PAUL, MINN. — The Stormwater Equipment Manufacturers Association (SWEMA) drafted a Maintenance Ordinance template for use by state and local government agencies in setting an ordinance requiring the maintenance of all stormwater Best Management Practices (BMPs). The ordinance addresses general requirements for stormwater BMPs, access requirements, maintenance frequency and inspection. The ordinance template is a general guideline and may be modified to suit state, local or regional requirements. 

Stormwater General Permits added to NPDES General Permit web inventory

WASHINGTON, D.C. — Under the Clean Water Act Action Plan (October 15, 2009), OECA and OWM committed to creating a website that features a national web-based inventory for all non-stormwater NPDES general permits issued by states and the Environmental Protection Agency (EPA). The web inventory went live in September 2012 and has now been updated to include stormwater general permits. The non-stormwater portion has also been updated with data current as of March 2013. 

U.S. EPA requires ADOT to reduce stormwater pollution

SAN FRANCISCO — The U.S. Environmental Protection Agency (EPA) reached an agreement with the Arizona Department of Transportation (ADOT) to improve the state’s stormwater management program as part of EPA’s national effort to reduce pollution of waterways by runoff from cities and statewide transportation agencies. ADOT manages 18,000 travel lane miles across the state, and stormwater runoff from its roads and maintenance facilities contain pollutants such as metals, sediment, oil, grease, pesticides and trash. 

Atlanta promotes green infrastructure policies to reduce stormwater pollution

ATLANTA — The Atlanta City Council unanimously adopted the amended Post-Development Stormwater Management Ordinance legislation drafted by the Department of Watershed Management that became effective Wednesday, Feb. 13, 2013. The ordinance promotes the use of green infrastructure practices in new and redevelopment projects in the city. The Post-Development Stormwater Ordinance is a requirement by a regional planning agency. However, the city went a step further to protect the property of its residents and businesses and reduce impacts to natural streams. 

Oldcastle Precast & Oldcastle Architectural announce U.S. launch of new LID stormwater management system

LITTLETON, Colo. – Oldcastle Precast and Oldcastle Architectural announce the U.S. launch of their new low impact development (LID) stormwater management system, PermeCapture™, an all-inclusive stormwater run-off control system that manages water volume in addition to protecting water quality by providing integrated pretreatment. PermeCapture combines the advantages and versatility of structural precast concrete modules (vaults) with the aesthetics and performance of permeable interlocking concrete pavers to provide a stand- alone, low maintenance, LID green solution for stormwater retention, detention, reuse, ground water recharge and flood management.

ASTM committee developing standard for stormwater hydrodynamic systems

W. CONSHOHOCKEN, PA. — Stormwater hydrodynamic (HDS) systems are used to remove settleable solids that could cause contamination from stormwater runoff. A proposed new ASTM International standard will be used to specify test material with a common target particle size distribution for use in testing HDS systems. 

EPA reconsiders stormwater discharge rule

WASHINGTON, D.C. — The National Association of Home Builders (NAHB), Utility Water Act Group (UWAG) and Wisconsin Builders Association settled a longstanding lawsuit against the U.S. Environmental Protection Agency (EPA) after the agency agreed to withdraw the numeric limit it developed to control stormwater runoff from construction sites and to pursue additional improvements to the 2009 rule. The lawsuit had noted that the EPA’s numeric limit would have cost stakeholders up to $10 billion a year in attempts to comply — and that coming up with a number that would work across all geographic areas and soil types would not be possible. 

Maintenance agreements, inspection checklists drafted for stormwater BMPs

ST. PAUL, MINN — The Stormwater Equipment Manufacturers Association drafted a new Maintenance Agreement for use by state and local government agencies in setting an ordinance requiring the maintenance of all stormwater Best Management Practices (BMPs). Stormwater BMPs are practices, whether land-based, proprietary or natural, that provide a level of treatment and/or storage to improve the water quality of the watershed. These practices in one form or another are installed on every project. Like a car, these practices require routine inspection and maintenance.
