Mississippi
Mississippi issues its own construction general permit. We have read Large Construction General Permit for Land Disturbing Activities of Five (5) or More Acres (MSR10) and list below the requirements we could cite to it, with the scope limits stated plainly. Screen your own acreage further down.
Who may prepare the plan
No preparer credential foundNo preparer credential was found for Mississippi. On what we have verified, a generated plan can be adopted by the operator without a credentialed signature. Local ordinances can still be stricter than state law.
No preparer credential found in the reviewed sources. Not exhaustively verified; confirm with the state agency and any local ordinance.
No permit section cited. Confirm this with your permitting authority.
Coverage trigger
The project disturbs 3 acres, at or above the 1 acre threshold, so it needs permit coverage.
The trigger people miss is the second one. A half acre lot inside a 40 acre subdivision is covered, because the larger common plan of development or sale is what counts, not the lot.
Worked for a three acre site with the receiving water unconfirmed. Each line says why it attached to this site rather than in general. Check the notes above for the site sizes this permit does not cover.
A site-specific SWPPP must be submitted together with the Large Construction Notice of Intent (LCNOI); owners/operators are authorized to discharge only upon receipt of written notification of approval of coverage.
Owners or operators are authorized to discharge storm water associated with large construction activity under the terms and conditions of this permit only upon receipt of written notification of approval of coverage by the Permit Board staff.
Within 30 days of final stabilization, a completed RFT form and photographs of the stabilized site must be submitted.
Within thirty (30) days of final stabilization (see Definition of Final Stabilization (1)) for a covered project, a completed Request for Termination (RFT) of Coverage form ... and colored photographs of the stabilized site shall be submitted to the Permit Board.
Inspection must be performed by qualified personnel at least weekly for a minimum of four inspections per month, and as often as necessary; controls and outfalls must also be inspected after rain events that produce a discharge.
Why this applies here: You have not confirmed whether the site discharges to an impaired or high quality water. If it does, the increased frequency applies instead and this answer changes.
Inspection of all receiving streams (if feasible), outfalls, erosion and sediment controls and other SWPPP requirements shall be performed during permit coverage ... shall be performed by qualified personnel: (1) At least weekly for a minimum of four inspections per month; and (2) As often as is necessary to ensure that appropriate erosion and sediment controls have been properly constructed and maintained.
A person knowledgeable in the principles and practice of erosion and sediment controls who possesses the skills to assess conditions at the construction site that could impact storm water quality and to assess the effectiveness of any sediment and erosion control measures.
Why this applies here: This is why Basinwise cannot perform your inspections. The permit requires a trained person physically on the site.
QUALIFIED PERSONNEL means a person knowledgeable in the principles and practice of erosion and sediment controls who possesses the skills to assess conditions at the construction site that could impact storm water quality and to assess the effectiveness of any sediment and erosion control measures selected to control the quality of storm water discharges from the construction activity.
Vegetative stabilization measures must be initiated whenever land-disturbing activities have ceased for 14 or more calendar days; 'immediately' means no later than the next work day.
Why this applies here: This applies at both land disturbance amounts.
Soil stabilization-vegetative stabilization measures must be initiated whenever any clearing, grading, grubbing, excavating or other land disturbing activities have temporarily or permanently ceased on any portion of the site and will not resume for a period of fourteen (14) calendar days or more.
As soon as possible, not to exceed 24 hours of the inspection (unless prevented by unsafe weather)
Any poorly functioning erosion controls or sediment controls, non-compliant discharges, or any other deficiencies observed during the inspections required under this permit shall be corrected as soon as possible, but not to exceed 24 hours of the inspection unless prevented by unsafe weather conditions as documented on the inspection form.
Temporary containment within 24 hours, permanent corrective measures within 5 days of the inspection.
In the event of an unanticipated breach of a sediment basin/pond, temporary containment measures shall be taken within 24 hours after the inspection. Permanent corrective measures shall be implemented within five (5) days of the inspection.
Provide and maintain a 50-foot undisturbed natural buffer around waters of the US, or a smaller buffer supplemented by equivalent controls.
Provide and maintain a 50-foot undisturbed natural buffer around waters of the United States; or provide and maintain an undisturbed natural buffer that is less than 50 feet and is supplemented by additional erosion and sediment controls which in combination achieves the sediment load reduction equivalent to a 50-foot undisturbed natural buffer.
MDEQ must be notified orally within 24 hours from the time noncompliance endangering health/environment is discovered.
The coverage recipient shall notify the MDEQ orally within twenty-four (24) hours from the time he or she becomes aware of unanticipated noncompliance, which may endanger health or the environment.
All records, reports, forms and information resulting from activities required by this permit shall be retained for at least 3 years from the date generated.
Why this applies here: The clock runs from permit expiry or termination, not from when the record was written, so on a multi year project every record stays live for the whole project plus three years.
All records, reports, forms and information resulting from activities required by this permit shall be retained for a period of at least three (3) years from the date that the document(s) was generated.

This is EPA's list, from the 2022 Construction General Permit. It does NOT govern in Mississippi, where the state issues its own permit and sets its own contents. It is here as a shape to expect, not as the requirement you will be held to.
Read the permit itself at the source document.
Mississippi issues its own construction general permit, and we have read Large Construction General Permit for Land Disturbing Activities of Five (5) or More Acres (MSR10). The requirements listed on this page, such as inspection frequency, who may inspect, stabilisation, corrective action and record retention, are cited to that permit rather than to EPA's. Anything we have not transcribed is left out instead of assumed to match the federal rule, and the scope note on this page says which sites the permit does not cover. Confirm the current permit and any site-size variant with Mississippi Department of Environmental Quality (MDEQ).
