July 13, 2021
The Stormwater Equipment Manufacturers Association (SWEMA), an industry association with diverse
membership consisting of innovative stormwater solution providers, laboratories, and other professional
organizations has been closely following the TAC progress as they develop recommendations for the
review and approval of proprietary and non‐proprietary stormwater best management practices (BMPs)
for use in Florida.

Letter to Massachusettes Department of Environmental ProtectionSWEMA feels that the communities making up the Commonwealth would benefit greatly from updated guidance on the vetting and use of innovative manufactured treatment devices (MTDs) for stormwater management. Given the many urban areas across the Commonwealth, the use of MTDs is common, but a lot has changed since MADEP published the existing guidance on this subject. The available MTDs have grown more diverse, many highly effective practices have been developed, and test standards and best practices have been refined considerably. Also, the defunding of the MASTEP initiative has left a major void since the stormwater handbook specifically references this now an obsolete resource.

TCEQ Review of Manufactured Treatment Devices; Needed Clarity on Review StandardsCompanies that desire to introduce their technologies to the Texas marketplace must show their technology meets the TCEQ criteria for MTDs. The current criterion includes an antecedent dry-period requirement between monitoring events of 72-hour minimum with less than 0.1 inches of rain. Current field monitoring programs consider a six-hour antecedent appropriate for stormwater monitoring.

SWEMA Submitted Comments on Proposed Changes to NJDEP Stormwater RegulationsThe Stormwater Equipment Manufacturers Association (SWEMA) strongly supports stormwater management strategies and regulations that incorporate advances in stormwater science, encourage innovation, and successfully protect and restore receiving waters at an affordable cost for our communities. The New Jersey Department of Environmental Protection (NJDEP) proposed changes to the New Jersey stormwater regulation will not promote these objectives. SWEMA members offered information on the proposed changes.

SWEMA's Response to City of Indianapolis Update to the Applicable Standards for the Evaluation and Acceptance of Manufactured Stormwater Treatment DevicesThe Stormwater Equipment Manufacturer’s Association (SWEMA) understands that the City of Indianapolis is currently in the process of updating the applicable standards for the evaluation and acceptance of manufactured stormwater treatment devices. Additionally, our understanding that once updates to the applicable criteria have been completed, all of the technologies currently approved by the City must be retested in full compliance with the updated criteria.

SWEMA's Response to "Proposed Use of Structural Stormwater BMPs In Alexandria."The Stormwater Equipment Manufacturer’s Association (SWEMA) represents a diverse group of stormwater solutions providers and supporting associate and professional members. Due to the diverse perspective and expertise of its membership, SWEMA is uniquely qualified to provide a professional perspective on the “Proposed Use of Structural Stormwater BMPs in Alexandria” document that is currently being considered for implementation within the jurisdiction of Alexandria Virginia.
SWEMA believes that all Stormwater BMPs, manufactured treatment devices, and generic green infrastructure BMPs, have appropriate and suitable applications. To remove one sector of BMPs limits a designer’s ability to provide sound engineering solutions to solve complex environmental conditions. In the past, the City of Alexandria has been one of the most innovative jurisdictions in the country by promoting sand filters and various underground stormwater devices. We commend the City of Alexandria for its unique history concerning advancing stormwater management (SWM) both regionally and nationally.
