Stormwater Simplified.

Contact us today to ensure your facility is taking all necessary steps to remain in compliance with these new regulations.

Comprehensive Permit Compliance

In the same way we help companies apply for and receive permit coverage, we also work with them to maintain their compliance moving forward.

The ongoing compliance requirements of the industrial stormwater permit (12-SW), the mineral mines permit (15-MM), and the marina permit (16-MA) are all slightly different, but they have more in common than not. All the permits require regular internal inspections, visual monitoring and lab testing of samples collected on-site during rain events, documented staff trainings about spill prevention procedures and other related topics, and more.


Grapewell’s Comprehensive Compliance Services


Some of the compliance services we provide to our clients throughout Maryland include:

Stormwater Sampling - All Maryland stormwater discharge permits require certain permit holders to collect stormwater samples, have them tested at a laboratory, and report the results on the relevant MDE/EPA database. This process can be confusing and expensive, which is why Grapewell offers a number of sampling services and products designed specifically to make the process as straightforward and affordable as possible.

Annual Comprehensive Inspections - All of Maryland's stormwater permits require permit holders to conduct comprehensive facility inspections on an annual basis. These inspections must be comprehensive in scope and must cover existing stormwater pollution prevention practices, procedures, and controls throughout the property in addition to providing suggestions for improvement. Our expert team conducts thorough inspections and provides all our clients with detailed and insightful written reports which can be used to document the effectiveness of controls and procedures and to plan future improvements.
