The stormwater permit for construction in Kansas

Kansas runs its own NPDES programme, so a state issued construction general permit governs. Below is what our engine can say about it, and where we have not read that permit, what it will not say.

Governing permit

Kansas Water Pollution Control General Permit and Authorization to Discharge, Stormwater Runoff from Construction Activities Under the National Pollutant Discharge Elimination System (General Permit No. S-MCST-2208-1, Federal Permit No. KSR100000)

Issued by: Kansas Department of Health and Environment (KDHE), Bureau of Water
Permit number: KSR100000
Version determined against: as published by the state agency
Effective: 2022-08-01
Expires: 2027-07-31

Who may prepare the plan

A credentialed preparer is required

Kansas requires a credentialed preparer. Treat the generated document as a complete draft for that person to review, adopt and sign. It is not by itself a compliant filed plan.

Qualifying routes

Kansas-licensed Professional Engineer (PE)
Kansas-licensed geologist
Kansas-licensed architect
Kansas-licensed landscape architect
Certified Professional in Erosion and Sediment Control (CPESC)

Every SWP2 (SWPPP) covered by this permit must be developed and prepared under the supervision of one of: a licensed Kansas PE, geologist, architect, landscape architect, or a CPESC — no acreage-based exemption or tiering exists in the permit text, so this applies uniformly to all sites the permit covers. A PE stamp is not independently required — PE licensure is only one of five equally valid qualifying routes. Part 6.1 separately allows continued use of the prior permit's SWP2 Plan for up to 18 months after this permit's effective date before this credential requirement kicks in for any modification.

Does a site in Kansas need coverage

Worked for a one acre site as a reference point. Change the acreage in the tool below and the answer, and its reasoning, change with it.

Coverage

Permit coverage required

Verified

The project disturbs 1 acres, at or above the 1 acre threshold, so it needs permit coverage.

Read these before you act on the answer

Requirements below are what we have read and cited directly from Kansas Water Pollution Control General Permit and Authorization to Discharge, Stormwater Runoff from Construction Activities Under the National Pollutant Discharge Elimination System (General Permit No. S-MCST-2208-1, Federal Permit No. KSR100000), not the federal CGP. A category we have not yet transcribed from this permit is omitted here rather than assumed to match EPA's rule.
The permit does not define a specific 'qualified' credential for the person performing routine site inspections (only the SWP2 Plan preparer must be a licensed PE/geologist/architect/landscape architect or CPESC), so inspection.qualifiedPerson is omitted. No increased inspection frequency for sensitive waters or reduced frequency for arid/semi-arid/drought conditions was found; KS instead has a distinct 'inactive site' reduced-inspection provision (modeled as state.ks.inspection.inactiveSite). KS does not use federal's acreage-tiered (<=5 acres / >5 acres) final stabilization completion structure -- it applies a single uniform 14-day stabilization-completion rule regardless of acreage -- so stabilization.complete.fiveAcresOrLess/moreThanFiveAcres were not used; a new state.ks.* id was created instead. No specific numeric-day deadline for filing the Notice of Termination (NOT) after project completion was found in the fetched text, so deadline.not.submission is omitted.
Kansas requires a credentialed preparer. Treat the generated document as a complete draft for that person to review, adopt and sign. It is not by itself a compliant filed plan.
Basinwise does not perform the physical site inspections the permit requires. Those must be carried out on site by a qualified person.

What to do next

1. Confirm the governing permit. Read Kansas Water Pollution Control General Permit and Authorization to Discharge, Stormwater Runoff from Construction Activities Under the National Pollutant Discharge Elimination System (General Permit No. S-MCST-2208-1, Federal Permit No. KSR100000) directly. It is linked above, and it is the document an inspector will hold you to. Kansas Department of Health and Environment (KDHE), Bureau of Water
2. Settle the preparer question before you draft. Getting this wrong costs a redraft at best. The detail is on the credential page for this state. Preparer credential in Kansas
3. Screen the site. Run the real acreage and receiving water facts through the tool below. You get the inspection frequency, the stabilisation deadlines and the filing path with the permit section behind each.

State*

Activity*

Total acres disturbed*

Total land disturbance over the whole project, including staging and access. This decides whether you need a permit at all.

Acres open at any one time

Optional. If you phase the work, the most that will be disturbed at once. Leave blank if the whole site is open together. The stabilisation deadline turns on this figure, not the total.

Part of a larger common plan of development or sale

A half acre lot inside a 40 acre subdivision is covered even though the lot alone is under the threshold. This is the most commonly missed trigger in the permit.

Receiving water and site conditions(optional, but they change the inspection frequency)

Discharges to a sediment or nutrient impaired water

Discharges to a Tier 2, 2.5 or 3 water

Arid, semi arid or drought stricken area

May allow a reduced inspection frequency during the seasonally dry period.

In Indian country

EPA keeps permitting authority in Indian country even inside a state that runs its own programme.

What people ask about the Kansas construction stormwater permit

Do I need a stormwater permit for a construction site in Kansas?

Permit coverage is triggered at one acre of land disturbance, and below one acre if the project is part of a larger common plan of development or sale that will ultimately disturb an acre or more. The project disturbs 1 acres, at or above the 1 acre threshold, so it needs permit coverage.

Kansas Department of Health and Environment (KDHE), Bureau of Water issues Kansas Water Pollution Control General Permit and Authorization to Discharge, Stormwater Runoff from Construction Activities Under the National Pollutant Discharge Elimination System (General Permit No. S-MCST-2208-1, Federal Permit No. KSR100000).
