Forms for Water Quality Review and Construction
Listed below are the forms required to help you complete the Water Quality review and construction process. Your project will be reviewed as a part of the Town's DRT Process. Please note that for all projects seeking a coverage, your submittal to the Town needs to contain the information and technical information necessary to meet the requirements of the 2021 State Construction General Permit, SCDHEC CZC, and any other Federal or State requirements. The resources provided below may not be ALL of the program requirements that your project may need to address.
Please review Town of Mount Pleasant Ordinance 153 for specific requirements for small residential, large residential, small commercial, large commercial, and utility projects. Other Codes such as Chapter 152 - Flood Damage Protection, Chapter 155 - Land Development, Chapter 156 - Zoning, and Chapter 158 - Encroachment Permits may also contain project requirements.
*****NEW 2021 SCDHEC Construction General Permit Issued*****
The SCDHEC reissued the NPDES General Permit for Stormwater Discharges from Construction Activities (SCR100000) on January 29, 2021. Please find below a link to the permit and the response to public comments. The permit will become effective on March 1, 2021.
Things to Know:
• In the coming weeks, DHEC staff will post a revised Stormwater Pollution Prevention Plan Template that construction site operators and consulting engineers may use.
• In the coming weeks, DHEC will post an updated form D-0451, auto-coverage form for very small projects in the coastal zone
• As noted in the Fact Sheet, the reissued permit is demonstrably similar to the previous permit. Please consult the Fact Sheet for specific updates.
• Construction site operators granted coverage under the previous permit are automatically covered under the reissued permit and do not need to submit a new NOI.
SCDHEC Notice Of Intent (NOI)
Notice of Intent forms need to be submitted to SCDHEC and the Town of Mount Pleasant when an applicant intends to perform land disturbance. A State NPDES permit is required for land disturbance greater than 1 acre, projects within a 1/2 mile of a coastal receiving water, less than 1 acre if part of a Larger Common Plan of Development (LCP) and some redevelopment projects. SCDHEC Construction Permitting website and forms
Projects within 1,000 feet of shellfish beds will have additional run-off retention requirements to meet. These requirements are listed in the State Construction General Permit and the Town's Code of Ordinances. Utilize the SCDNR Intertidal Oyster Mapping Tool to evaluate your site.
Coastal Zone Consistency Review (CZC)
The State's Office of Coastal Resource Management (OCRM) reviews construction projects within 2 miles of the coast for program consistency. Review the OCRM CZC Website for specific requirements and forms.
Town Drainage Master Plan Checklist
Prior to submitting a project for review, engineers and developers should complete the Town's Drainage Master Plan Checklist for new construction and redevelopment projects with one acre or more of land disturbance. Access the Town's checklist here.
SCDHEC Plan Review Checklist
SCDHEC has developed a new checklist for the State's 2012 Construction General Permit to assist Design Professionals in completing submittals for the new permit requirements, the checklist is an aid and not a substitute for the full permit requirements or language. Access the State's checklist here.
Town Encroachment Permits
Town Encroachment Permits may be needed for projects that will impact either Town Right of Ways or Drainage Easements. Special restrictions apply to these areas and special permits may be needed with plan submittals and approvals. Encroachment Permits will be processed by the Town's Transportation and Capital Projects team on the DRT.
NPDES Fee Schedule
The Town charges Water Quality plan review and inspection fees for all projects needing an MS4 review. Complete the form and submit the form and fees with your final application. * Please note that other Town fees may also apply. Please confirm with the Planning and Development Department. Access the NPDES Fee Schedule form here.
Certificate of Compliance
Owners of small construction sites (disturbing under 1 acre and not part of a Larger Common Plan (LCP) are required to complete and submit the Certificate of Compliance for the Town of Mount Pleasant. The Certificate of Compliance details specific site controls and processes that will occur on these smaller sites. These projects are subject to random inspections to ensure that sites are being properly maintained and are not discharging pollutants. The Certificate of Compliance is a triplicate form and can be obtained through the NPDES Coordinator or Building Inspections Department. Access the Certificate of Compliance form here.
Some small sites, if the project involves the installation of permanent water quality systems or devices, will be required to submit for a mini-technical review, obtain a Town Clearing and Grading Permit, provide maintenance agreements, and submit as-built drawings.
The Town will not be reviewing the SCDHEC Individual Lot NOI form. The Town's Certificate of Compliance will be submitted with the building permit application but does not replace the requirement to obtain State Permits for individual lot construction in a Larger Common Plan of Development. Clearing and Grading permits are not processed by Stormwater for individual lots, the building permit will serve this function. Sites need to maintain SWPPP compliance and inspections.
Clearing and Grading Permit
Projects can apply for a Clearing and Grading permit once Water Quality approval has been received from the Town and all State and Federal Permits have been received. Installation for the Clearing and Grading permit cannot begin until your project receives its Construction General Permit (CGP) from SCDHEC. Additional clearing other than for installation of BMPs is strictly forbidden. BMPs for the Clearing and Grading inspection include silt fence, inlet protection, tree protection, and construction entrance. Access the Clearing and Grading permit application here.
NPDES Compliance Inspection Report for Contractors
** Please note that the Town expects all sites to comply with their plans and permits. A SWPPP inspector's notation of corrective actions MUST be addressed within 7 days. Some plans call for shorter response times. Measures that fail repeatedly may be required to be replaced or upgraded.
Final Inspection Checklist
The Final Inspection Checklist will help you close out the construction phase of your residential development project. It details the minimum processes or items for inspection that will need to be completed before you can be granted your Final Plat. Town Inspectors for Road Construction, Stormwater Infrastructure Installation, and Water Quality BMPs will conduct a project walk-through to examine your project. The Town provides a checklist of the minimum items for inspection used to evaluate if your project is complete. Access the checklist here.
Commercial Project - Certificate of Occupancy (CO)
Commercial sites will need to pass at least two inspections to complete their project - a Civil Inspection for Certificate of Occupancy (CO) and the NPDES Final inspection. Inspections should be coordinated with your Town SWPPP inspector and the Building Coordinator; especially for phased projects. As-builts of the site will need to be submitted and accepted prior to issuance of CO. Projects with public infrastructure will also need to complete CCTV and document submittals. It is preferred that the site obtain a CO and Notice of Termination (NOT) at the same time - exceptions can be made for phased projects or shell projects with prior coordination/ approvals. Site stabilization may not be enough to obtain a NOT if there are ongoing (interior) construction activities that may generate construction pollution (such as trash or paint/ concrete washout).
As-builts are required for most projects to allow project engineers to review the built condition and confirm/ certify that the project was built according to their plans. The information is also used to manage the post-construction BMPs and infrastructure. DRAFT As-built submittal should be made well in advance of project closeout to allow for review, comment, and corrections. To expedite your process and approval, please follow the as-built checklist and submit the checklist form with your documents. Access the as-built checklist here. Upon acceptance, a signed PDF of the as-built, a .dwg file, and a GIS file will be required.
Stormwater Facility Maintenance AgreementAll new projects reviewed by the Town of Mount Pleasant that have installed BMPs as part of their stormwater drainage plan are required to submit a Stormwater Facility Maintenance Agreement to the Town. Access the agreement form here. To find out more information on long-term maintenance requirements for your project or property, check our Post-Construction Process page.
SCDHEC and OCRM may require additional submittals to receive State approval for land disturbance. Visit their websites to access other forms and applications that may be necessary.
