WHERE THE MONEY GOES.
Clean Water Act stormwater penalties run to $56,460 per day per violation at current EPA inflation-adjusted rates, with negligent-violation criminal exposure of $2,500 to $25,000 per day plus potential jail, and knowing violations at $5,000 to $50,000 per day. State boards stack their own: California water code carries $10,000 per day per violation category, and one enforcement file alleged 148 days of missed inspections alone. A stop-work order arrives with the citation. For the SWPPP contractor, the client's fine risk IS the product; for the SWPPP contractor's own compliance, it's existential.
THE COST, SOURCED.
"EPA fines for SWPPP violations can reach up to $56,460 per day per violation." (CRG Texas, 2025) Negligent/knowing tiers per EPA via Erosion Control Services; CA $10K/day categories per Lahontan water board enforcement attachment.
THE NUMBER TO MEASURE IT AGAINST.
SWPPP and Erosion Control contractors run about % net profit at $1M to $5M, rising to roughly 13% at $5M to $10M. The CFOS target at $1M to $5M is11%, set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher. A problem like this one lives in the distance between those two figures rather than in a loss on any single job.
Gross margin over the same bands runs % to 26%, against a CFOS target of 11%.
