NOTICE OF INTENT (NOI)

For Authorization to Discharge Stormwater Runoff from Construction Activities In accordance with the Kansas Water Pollution Control General Permit Under the National Pollutant Discharge Elimination System (NPDES)

Submission of this Notice of Intent constitutes notice that the party identified in Section I of this form requests authorization for coverage under the Kansas Water Pollution Control general permit, or KDHE issued successor permits, issued for stormwater runoff from construction activities in the State of Kansas. Becoming a permittee obligates the discharger to comply with the terms and conditions of the general permit. A complete request for Authorization for coverage under the general permit must be submitted or the request will not be processed. KDHE will notify owners or operators whose Notice of Intent (NOI) and supporting documentation for Authorization of stormwater runoff associated with construction activities are incomplete, deficient, or denied.

B. Existing Conditions/Uses

1) Is any part of the project located on Indian Country Land?

No

2) If stormwater runoff drains to or through a Municipal Separate Storm sewer System (MS4): MS4 Name:

3) Name of the first receiving water, stream, or lake Cowskin Cr (1103001310), River Basin AR -

LOWER ARKANSAS

4) Are contaminated soils present on the site or is there groundwater contamination located within the site boundary?

No

5) Are there any contaminated soils that will be disturbed or any contaminated groundwater that will be pumped by the proposed construction activity?

No

6) Are there any surface water intakes for public drinking water supplies located within ½ mile of the site discharge points?

No

7) Are there any known historical or archeological sites present within the site boundary or any historic structures located within 1000 feet of the project site?

No

Note: Include documentation of project-specific coordination with the Kansas Historical Society in making this determination

8) Is any threatened or endangered species habitat located within the site boundary or in the receiving water body?

No

Note: Include documentation of project-specific coordination with the Kansas Department of Wildlife, Parks & Tourism in making this determination.

9) Will the project impact the line or grade of a stream or does it include dredge or fill of a potential jurisdictional water body or wetlands?

C. Project Description

1) Project Description:

Construction of 32 residentials units which includes paving, water, sanitary sewer and storm sewer improvements to the site.

Does this NOI include all proposed soil disturbing activities associated with the entire common plan of development? Yes

2) Anticipated project Start Date: December 1, 2025 and Completion Date: May 31, 2026

3) Estimated total area to be disturbed: 10.50 Acres

4) Total area of the site: 10.50 Acres

5) Do you plan to disturb ten or more acres that are within a common drainage area? Yes

Will a sedimentation basin be installed in that drainage area? Yes

(Attach design calculations for each sedimentation basin.) If a sediment basin is not feasible, on a separate sheet describe similarly effective erosion and sediment control measures to be implemented in lieu of a sedimentation basin.KEIMS Watermark

D. Maps

Include an area map showing the outline of the construction site and the topographic features of the area at least one mile beyond the project site.

E. Erosion Control Plan and Best Management Practices

1) Provide a summary of the sequence of major soil disturbing activities including installation of the corresponding stormwater management and pollution control features.

Underground utilities will be installed with silt fence put up for drainage protection. Site grading will follow which includes creating a pond for the entire site.

2) Provide one or more site plans covering the anticipated soil disturbing activities showing the limits of disturbance, the existing and proposed elevation contours, the types and locations of erosion/sediment control measures and stormwater management/pollution control features during each phase of construction and the locations where stormwater runoff leaves the construction site.

3) Provide a description of the best management practices to be utilized to control erosion and the discharge of sediment and other pollutants in stormwater runoff throughout construction and the design calculations for each sediment basin including total drainage area and storage capacity below the elevation of the mass volume flow outlet device.

Approximately 10.5 acres will be disturbed within a common drainage area. The outflow of the proposed pond will temporarily be 1392 ft to allow on-site sediment to accumulate.

10.5 acres X 3600 cf / acre = 37,800 cf storage required

Pond Volume Calculation 31,253 sf (Approximate temporary outflow) 12,559 sf (Approximate pond bottom) Volume = (31,253+12,559) sf / 2 x 7’ depth = 153,342 cf provided

4) Provide the name and License or Certification Number of the engineer, geologist, architect, landscape architect, or Certified Professional in Erosion and Sediment Control (CPESC) under which the construction stormwater pollution prevention plan has been developed.

III. ANNUAL FEES

The first year of the annual permit fee specified in K.A.R 28-16-56 et seq. as amended is currently $60.00 and can be paid through the KEIMS system at time of submittal. The fee must be paid before this NOI will be processed. An invoice for the annual permit fee will be sent to the contact person requesting a permit until such time as the permittee submits a Notice of Termination (NOT).

Failure to pay the annual fee timely may result in termination of the construction stormwater discharge Authorization.

IV. OWNER OR OPERATOR CERTIFICATIONS

I, the undersigned, certify that a Stormwater Pollution Prevention Plan (SWP2 Plan) will be or has been developed for the construction site described in this NOI and supporting documentation. I further certify that the plan will be implemented at the time construction begins, and, as required by the NPDES general permit for Stormwater Runoff from Construction Activity, will revise the SWP2 plan if necessary.

I understand that continued coverage under the NPDES general permit for Stormwater Runoff from Construction Activities is contingent upon maintaining eligibility as provided for in the requirements and conditions of the general permit, and paying the annual fee. KEIMS Watermark
