Stormwater Compliance Intro for Vertical Construction Subcontractors
Failure of the governing municipality (MS4) to assure compliance by the contractor and failure of the contractor to follow the stormwater requirements of the permit can bring non-compliance actions of fines for the city and/or the contractor, and even cause the construction project to be shut down.
To prevent pollutants or sediment from leaving the construction site, there should be
You should refer to the SWPPP and SWPPP map to see what BMPs (Best Management Practices) are being utilized and where all BMPs are supposed to be. You can ask the project manager or site superintendent for access to or a copy of the SWPP
Stormwater Compliance Inspections and Corrective Action Requirements for Vertical Construction Subcontractors
Under stormwater regulations, there will be regular site inspections to identify if there are any problems with the site BMPs. If a problem is identified, it will be noted as a corrective action item that must be remedied within a specified time period, usually 7 days or less.
You should communicate closely with the project manager and site superintendent regarding any concerns with the stormwater requirements for the project. Be sure you are familiar with the SWPPP and SWPPP map.
Dirt ramps should never be used to gain access to the site. If necessary, other kinds of ramps should be used, such as silt sifter bags, rubber bags, or asphalt bags.
When hauling materials onto the site, be sure you are entering at designated entrances. If there is a designated exit on the lot, then you should always exit there. You must avoid tracking sediment from the lot. Tracking applies to all vehicles and equipment. If you don’t need to drive onto the site or onto the lot then keep your vehicle on the street.
StabIlized exits are often done by using rocks large enough to shake the vehicles so that dirt is not tracked out of the exit. A geotextile should be placed under the rock to prevent the rock from being pushed down into the sediment or mud. Sometimes washing of tires is necessary to assure no tracking from the site. If trackout does occur, then it needs to be swept up as soon as possible, no later than the end of the day.

Washing of applicators must be done in a designated washout. Washout waters should never be on the dirt. The washout can be a specific washout or the concrete washout. If
At the end of each day, all trash and debris will need to be cleaned up and contained within the dumpsters on site. The trash and debris need to be contained on-site and properly disposed of. The site needs to be kept clean and organized. Once storm inlets are installed, you should be careful not to damage the inlet protection.
