Free screening
Screen a site against the permit that governs it
No account, no card, and no request. The engine that answers this is the same one behind the API and the paid product, and it runs in this tab, so your location, acreage and dates are never transmitted.
Enter the site
State, activity, and the acreage the project will disturb. Say whether it is part of a larger common plan of development or sale, which is the trigger most people miss.
Add what you know about the receiving water
Whether the site discharges to a sediment or nutrient impaired water, or a Tier 2, 2.5 or 3 water. If you have not checked, leave it as not checked and the answer will say so rather than assume.
Read the determination
The coverage verdict, the governing permit, the requirements with the permit section behind each one, the eligibility screens and the credential gate, plus the full derivation so every conclusion shows its reasoning.
We do not perform site inspections
The permit requires a physical inspection by a qualified person on a schedule, and that person has to be standing on the site. We generate the plan and maintain the inspection record. We are a compliance documentation engine, not compliance.
In credential gated states our document is a draft
Where a state requires a credentialed preparer, what we generate is a complete draft for that person to review, amend and sign. It is not by itself a filed plan, and it says so on the document. We would rather lose the sale than have you file something that is not valid in your state.
An unread jurisdiction reads as unread
Where we have not read a state's permit we do not print a plausible number. The page says not verified, names the agency and links it. We never infer a requirement we did not read in a permit, and an honest gap always beats a confident guess.
Basinwise reports publicly published permit requirements and cites the permit section behind each one. It is not legal or engineering advice and it is not a permit. We do not perform the physical site inspections the permit requires; we generate the plan and keep the record. Where a jurisdiction requires a credentialed preparer, the document we generate is a draft for that person to review and sign. Always confirm against your permitting authority's current permit before you break ground.
Screening answers the question. The permit makes you keep the record.
A covered operator must hold a written site specific plan and retain the inspection and corrective action log for years. That is the paid product.
