Expert NPDES Erosion Control Services & Compliance

NPDES stands for National Pollutant Discharge Elimination System. In construction, it refers to permit requirements for managing stormwater runoff from disturbed sites so sediment, concrete washout, pollutants, and other contaminants do not enter waterways. Projects typically use a stormwater pollution prevention plan, best management practices, inspections, and maintenance to control erosion and discharge quality.

Best practices include stabilizing disturbed soil quickly, protecting slopes and channels, slowing runoff, filtering sediment before it reaches inlets, and using properly selected materials such as sediment logs, erosion control blankets, turf reinforcement mats, turbidity curtains, and inlet filters. Effective erosion control also requires routine inspection, maintenance after rain events, and adjustments as site grades and drainage patterns change.

Erosion and sediment control products help construction teams implement the best management practices described in stormwater plans. Materials such as rock bags, sediment logs, inlet filters, dewatering bags, and washout containment reduce sediment movement and pollution risk. Coleman Moore Company helps match these products to site conditions, which supports better field performance and more consistent compliance documentation.

Common runoff control products include erosion control blankets for exposed soil, turf reinforcement mats for channels, sediment logs and rock bags for perimeter control, inlet filters for storm drains, turbidity curtains for water-adjacent work, and dewatering bags or filtration tanks for pumped water. The right mix depends on slope, soil type, flow volume, access, and construction phasing.

Coleman Moore Company can provide product recommendations, material quotes, design assistance, product analysis, and installation consultation for erosion control, sediment control, water quality, and stormwater management needs. While permitting responsibilities remain with the project owner or qualified professionals, the team helps select practical materials that align with site requirements and best management practice goals.

Dewatering solutions include dewatering bags, filtration tanks, portable sediment containment systems, flocculants, and other water quality products. These materials help remove solids and sediment particles from pumped water before discharge. Coleman Moore Company can help determine whether a bag, tank, chemical treatment, or combined approach is appropriate based on flow rate, sediment load, and project duration.

Concrete washout bags contain wash water and concrete waste from ready-mix trucks, drums, and pumps, helping prevent high-pH washout from contaminating soil, storm drains, or water sources. Coleman Moore Company supplies durable polypropylene washout bags in multiple sizes. Once filled, bags can be transported to a landfill or separated for concrete recycling where appropriate.
