As regulatory requirements become more stringent and more emerging pollutants are identified, research is necessary to develop solutions Permittees can apply to meet their MS4 Permit and Underground Injection Control (UIC) Program Rule requirements. At Evergreen StormH2O, we pride ourselves on staying at the forefront of stormwater management trends, practices, and regulatory requirements. Our unique approach builds upon our team’s extensive experience in all aspects of stormwater, with a focus on designing our studies and developing solutions that meet regulatory requirements and our clients’ visions. We work collaboratively with clients to develop customized solutions they can apply in the field, and we work one on one with maintenance staff to develop sustainable maintenance practices for stormwater infrastructure and BMPs.
Our staff have assisted clients in navigating the rigorous Technology Assessment Protocol – Ecology (TAPE) process to develop new and emerging treatment technologies that are approved for general use to reduce regulated pollutants. Our work experience ranges from developing new media to bench and flow through column testing to monitoring client-developed technologies in the field.
QAPPs are required for all environmental studies conducted for both Ecology and the EPA. Our staff have extensive experience developing Ecology-approved QAPPs and developing procedures that were adopted by Ecology for stormwater and environmental studies.
Our staff have comprehensive experience evaluating the effectiveness of stormwater management programs to support jurisdictions in meeting the MS4 Permit requirement S8 for Monitoring and Assessment of structural, operational, and educational BMPs. Our staff's research projects have focused on natural dispersion, bioretention media, biofiltration swales, wetlands, vegetated filter strips, permeable pavement, sand filters, street sweeping, catch basin cleaning, and numerous education and outreach studies including behavior change campaigns.
Our staff have designed and installed monitoring equipment to collect flow, precipitation, and water quality data to meet MS4 Permit requirements for Total Maximum Daily Loads (TMDLs), as part of an effectiveness study and to support new treatment technology development. Our approach is to develop a plan and system that meets regulatory and TAPE requirements (if applicable). We collect only the data needed to answer the research questions and support the quality assurance plan, which keeps the overall cost of this work down.
