Stormwater Permitting
In every construction or development project, there is a responsibility to manage stormwater runoff effectively. At Capital Environmental Consultants, we help clients meet this responsibility by preparing Stormwater Pollution Prevention Plans (SWPPPs) to obtain NYCDEP Stormwater Construction Permits and gain coverage under the NYSDEC State Pollutant Discharge Elimination System (SPDES) General Permit for Stormwater Discharges from Construction or Industrial Activities.
Our team translates complex permit language into clear, actionable requirements, ensuring your site remains compliant and water quality is protected from the first day of construction through final stabilization.
Understanding the SWPPP
A Stormwater Pollution Prevention Plan (SWPPP) is a site-specific document required for compliance with the National Pollutant Discharge Elimination System (NPDES) program under the federal Clean Water Act, detailing how a project will prevent pollutants (e.g., sediment, oil, nutrients) from reaching nearby surface waters, wetlands, or municipal systems during and after construction. A well-crafted SWPPP identifies potential pollutant sources and discharge points, outlines the erosion and sediment controls and stormwater management practices to be implemented, and sets clear inspection and reporting procedures to ensure full compliance with all federal, state, and local permitting requirements.
When a SWPPP Is Required
In New York City, the state’s only large Municipal Separate Storm Sewer System (MS4), a SWPPP is required for any project that disturbs 20,000 square feet of soil or creates 5,000 square feet of impervious area. In New York State, a SWPPP is generally required for any project that disturbs one acre or more of soil, or for work that is part of a larger common plan of development, in order to obtain coverage under the SPDES General Permit for Construction Activity. This requirement applies to residential subdivisions, commercial, industrial or institutional developments, roadway or utility construction, municipal infrastructure upgrades, site redevelopment, and demolition projects that involve soil disturbance.
Many industrial operations are required to develop a SWPPP, inclusive of best management practices (BMPs), to prevent stormwater from interacting with outdoor industrial activities and minimize the discharge of pollutants and ultimately gain coverage under the SPDES Multi-Sector General Permit for Stormwater Discharges Associated with Industrial Activities (MSGP). These requirements vary based on a facilities Standard Industrial Code (SIC) and the associated pollutants common to each industrial activity performed onsite.
Our Stormwater and SWPPP Services
SWPPP Preparation & Development
Each SWPPP is developed for a specific site, including its topography, soil characteristics, hydrology, and pollutant sources. We guide the design of practical Stormwater Management Practices (SMPs) based on hydrological analyses that meet regulatory standards and are realistic for on-site implementation.
Plans typically include:
- Erosion and sediment control (E&SC) plans for each phase of construction
- Site maps showing flow direction, discharge points, and SMP locations
- Hydrological analysis
- Post-construction stormwater management practices
- Final stabilization criteria
- Inspection and maintenance schedules
For industrial facilities, we prepare and maintain SWPPPs under the Multi-Sector General Permit (MSGP). Services include site evaluations, pollutant source identification, structural and non-structural Best Management Practice (BMP) design, sampling protocols, and reporting.
Implementation and Training
Compliance depends on proper implementation. We guide contractors and project managers through review of the SWPPP details and explain the purpose and installation of each E&SC measure. This helps ensure that field crews understand both the technical and regulatory importance of compliance.
Inspections and Reporting
We guide contractors and project managers through routine site inspections in accordance with permit requirements, documenting site conditions and verifying E&SC and SMP effectiveness. Inspection report templates are prepared to meet NYSDEC, NYCDEP, and municipal submittal standards and serve as a record of your compliance.
Revisions and Permit Updates
Construction projects evolve. We amend SWPPPs to reflect site changes, design modifications, or new regulatory requirements, keeping your documentation current and accurate throughout the project lifecycle.
Site Close Out and NOTs
Upon final stabilization of a construction project, we close out state and local stormwater construction permits through receipt of NYCDEP Maintenance Permits and NYSDEC Notice of Termination filings. Our team ensures all submittals are accurate, timely, and properly coordinated with agencies and municipalities.
Quality and Quantity Control
Effective stormwater management must balance both water quality and water quantity, ensuring that runoff is slowed to prevent downstream flooding and erosion, treated through filtration, infiltration, or detention, and carefully managed to avoid combined sewer overflows in urban systems. In New York City, that often means designing compact, engineered treatment systems that filter runoff before it enters the municipal sewer network or groundwater, while upstate projects can take advantage of larger footprints that allow for infiltration basins, bioretention areas, and other landscape-based practices tailored to broader sites.
I am pleased to provide this testimonial for Capital Environmental Consultants.
I have worked closely with Greg and Kelly on numerous projects involving DEC and DEP matters, including one of the most critical components of our development work — MS4 compliance. Their knowledge, responsiveness, and ability to navigate complex regulatory requirements were instrumental in moving our project forward.
Capital Environmental Consultants handled the design, approvals, and permitting process efficiently and professionally, ultimately allowing us to obtain DEP sign-off without delays. Their understanding of the regulatory landscape and attention to detail gave us confidence every step of the way.
I would highly recommend Greg, Kelly, and the entire team at Capital Environmental Consultants to anyone in need of experienced and reliable environmental consulting services.

Capital Environmental is a small shop with big shop capabilities!
Greg Fleischer has unparallelled knowledge and experience in handling wetlands and natural resource regulatory issues. He’s performed time and again on complex development projects where everything is on the line. Greg is respectful but does not shy away from a tough task or a hard fight. Kelly is one of the most remarkable stormwater regulatory experts with whom I’ve had the pleasure to work. Her attention to small but critical details is unmatched, while she also maintains a nuanced understanding of the big picture. And Kelley is always there for her clients and colleagues—the definition of a team player.
I would not hesitate to go with Capital on a complicated development project where wetlands, stormwater or natural resources are at issue—and they are always at issue.
