Frequently Asked Questions
What is Danvers's NPDES Notice of Intent, and what does it require of the town?
Danvers received Notice of Intent approval from the EPA and the Massachusetts Department of Environmental Protection on April 5, 2019, authorizing stormwater discharge from its municipal separate storm sewer system under the terms of the MS4 General Permit. Under the permit’s illicit discharge detection and elimination plan, the town is required to perform dry weather outfall screening and sampling, completed within three years of the permit’s effective date.
What has to be included in an Operation and Maintenance Plan for a Danvers property?
Beyond standard site information, the plan must show the location of all stormwater facilities and best management practices, including catch basins, manholes, and pipes. It also needs contact information for the property owner and whoever is responsible for site operation, maintenance, and financing repairs, along with a full inspection and maintenance schedule detailing what tasks are performed, when, and by whom.
When does a Danvers property need a stormwater management easement?
Stormwater management easements are required for any areas used for off-site stormwater control, unless the Stormwater Authority grants a waiver. Easements must cover access for facility inspections and maintenance, preservation of runoff conveyance and detention areas including flood routes for a 100-year storm event, and direct maintenance access for heavy equipment.
How often are stormwater facilities inspected under a Danvers maintenance agreement?
At minimum, inspections must occur once a year. Privately owned stormwater management systems need an executed maintenance agreement between the owner and the Stormwater Authority that names the responsible party for conducting these ongoing inspections.
How long does a Danvers property owner need to keep stormwater maintenance records?
Records of installation, maintenance, and repairs must be retained for the most recent five years. These records need to be available to the Stormwater Authority during facility inspections and provided upon request at any other time.
What happens if a Danvers project can't meet a stormwater management standard?
If the applicant believes a standard or requirement can’t reasonably be met, the stormwater report must include a detailed explanation of why, along with a description of the potential consequences if no mitigating measures are put in place.
