MMayfield Environmental Solutions is an MBE/DBE General Contractor in Southern California with decades of experience in Stormwater Pollution Prevention Planning (SWPPP & NPDES) Services, Erosion and Runoff Mitigation, Environmental Site Assessment (ESA), BMP Installs, Hydroseeding, BMP Installations, Sandbag and Wattle/Compost/Geotextile installation, and Waste-Water Pumping & Dewatering services. Let us do your Water Quality Testing for PFAS (“Forever Chemicals”), Lead, Radon Gas, and more.
We’ll be your comprehensive Water Board partners from start to finish. In California, ANY industrial or manufacturing facility MUST obtain an NPDES (National Pollutant Discharge Elimination System) Permit from the Water Board to remain compliant with the Industrial General Permit (IGP), including regular inspections by a QISP (Qualified Industrial SWPPP Practitioner) like ours.
Industries legally cannot certify themselves. They require a QSD (Developer) like ours to obtain a Permit. If you qualify, we will try to get you a NONA or NEC (No Exposure Certification) to avoid Inspection costs.
Otherwise, a QISP must regularly inspect your development’s BMPs (Best Management Practices) to prove to the Water Board that chemicals, sediment, or waste from your production does not end up in storm drain inlets or off-site. These inspection reports must be posted publicly in order for you to remain compliant with the IGP and the Water Board.
For ALL industries, you are required to have a QISP sample rainwater on your site for “TMDLs” (Total Maximum Daily Load) of contaminants based on whatever local water source is at risk. We’ll help manage your local TMDLs, sediment load, pH, turbidity, and other key environmental risk factors.
We are the ONLY company in SoCal that can simultaneously offer certified SWPPP/NPDES/QSP/QISP inspections for Water Board Compliance, our own QSDs to design & certify SWPPPs, provide our own field labor to install BMPs and maintain GCP/IGP permitting, and miles of fire hose for Waste-Water Pumping and Hydroseeding. We also do Sewage Cleanups/Sewer work with proper vacuuming/pumping services, respirators, and H2S/hydrogen sulfide and oxygen monitoring protocols.
We provide our own testing equipment for water quality, pH, Turbidity, TSS (Total Suspended Solids), and TMDL/NAL discharge limit exceedances to ensure compliance, which cuts down on rental costs for you.
We are also experts in Green Stormwater Infrastructure (GSI) design and installation, being the only contractor in Southern California who can combine our landscape architecture licenses (C-27), soil management and erosion protection licenses, Water Board and stormwater licenses, and civil engineering licenses for your project.
We’ll help make your Jobsite, Development, Brownfield, or Property compliant with Industrial General Permit Regulations, as we’ve worked closely with QSPs (Qualified SWPPP Practitioners) and QSDs (Developers) for decades.
