Less Than One Acre (Not Part of LCP)
Project Requirements In Non-Coastal Counties
This document provides guidance for projects that disturb less than one (1) acre; are not part of a larger common plan for development or sale
(LCP); and are located outside of the 8 coastal counties (Beaufort, Berkeley, Charleston, Colleton, Dorchester, Georgetown, Horry and Jasper)
subject to the requirements of the S.C. Coastal Zone Management Plan. ; and are not part of a MS4 or Urbanized Area (UA). If the less than
one (1) acre project is to be constructed in a MS4 or urbanized area, the respective MS4 or UA must be consulted to identify applicable project
requirements. The Wheretoapply guidance may also be consulted for MS4/UA contact information.
Regulatory Basis: The S.C. Stormwater Management and Sediment Reduction Act (R.72-300) requires that for land disturbing activities involving two
(2) acres or less of actual land disturbance which are not part of a larger common plan of development or sale, the person responsible for the land
disturbing activity shall submit a simplied stormwater management and sediment control plan meeting the requirements of R.72-307H. In addition
to R.72-300, all projects that disturb 1 acre or more are subject to the requirements of the NPDES General Permit for Storm Water Discharges from
Large and Small Construction Activities (CGP). Additionally, projects may be subject to requirements of local governments through local ordinances, in
particular, those areas that are considered Municipal Separate Storm Sewer Systems (MS4s) under the NPDES program. Please see http://www.scdhec.
gov/environment/water/swnsms4.htm for more information. This specic guidance addresses requirements only for less than one (1) acre non-
coastal projects that are not part of a LCP.
Denition LCP: The plan in LCP is “broadly dened as any announcement or piece of documentation (including a sign, public notice or hearing, sales
pitch, advertisement, drawing, permit application, zoning request, computer design, etc.) or physical demarcation (including boundary signs, lot stakes,
surveyor markings, etc.) indicating construction activities may occur on a specic plot.” [63 Federal Register No. 128, July 6, 1998, p. 36491] For
example, if master calculations have been prepared and/ or submitted for an entire site, then all phases and parcels at that site would be considered part
of an LCP. If the site is part of a subdivision, industrial park, commercial park, etc., then it is considered to be part of an LCP. If there have been land-
disturbing activities, including clearing, grading or excavating, that resulted in one (1) disturbed acre or more since 1992, then any future land-disturbing
activities at the site are considered to be part of an LCP.
Less Than One (1) Acre Non-Coastal Project Requirements:
Projects that disturb less than 1 acre and are not part of a larger common plan for development or sale (LCP) require the submittal of a simplied
plan sheet and Notication Form (DHEC Form 2628) or other form provided by DHEC. Please note that stormwater detention is not required under
R. 72-300 for projects in this program area, however, these projects are required to provide adequate sediment and erosion controls in order to
insure no offsite sedimentation into Waters of the State, adjacent properties, and public right-of-ways. Please also note that the Department
does not regulate the placement of ll in oodplains. You must contact your local city or county ofcial for such approval. Following is a
summary of DHEC’s submittal requirements for non-coastal projects that disturb less than one (1) acre and are not part of a LCP or MS4/UA:
Provide 1. one (1) complete (signed and dated) Notication Form (DHEC Form 2628) or other form provided by DHEC. Note: The Notication
form must be signed and dated by the Project Owner/Operator.
Provide 2. one (1) copy of the plan/sketch. Note: Plan is not required to be prepared by an engineer, Tier B surveyor, or landscape
architect; however, if an individual with one of these licenses prepares the plan, then they must sign and seal the plans. The sketched
plan should include:
(a) A site location drawing of the proposed project, indicating the location of the proposed project in relation to roadways, jurisdictional
boundaries, streams and rivers; (b) The boundary lines of the site on which the work is to be performed; (c) The location of temporary
and permanent vegetative and structural stormwater management and sediment control measures; and (d) A topographic map of the
site (if required by the implementing agency).
A 3. narrative description of the stormwater management and sediment control plan to be used during land disturbing activities. Note: This may
be included on the plans instead of in a written narrative. Include a general description of topographic and soil conditions of the property.
Include a general description of adjacent property and a description of existing structures, buildings, and other xed improvements located on
surrounding properties.
Once completed, the notication package (form, plans, and narrative) may be e-mailed (as pdf) to Stormwaterlessthan1@dhec.sc.gov for electronic
processing by the Bureau of Water. A notice of receipt will be e-mailed to the applicant upon successful receipt of the notication package.
Once the notication package has been screened for completeness and applicability, a letter requesting additional information or an approval
letter will be e-mailed to the project owner/operator at the e-mail address provided on the notication form. If electronic submittal is not possible
or desired, Less Than One Acre notications may be mailed to SCDHEC - Bureau of Water, Stormwater Permitting Section, 2600 Bull Street, Columbia,
