SECTION 101.0 SCOPE
101.1 Title: These regulations shall be known as the "Land Disturbance Code" of St. Louis County, Missouri, hereinafter referred to as "this Code".
101.2 Introduction: On construction or land disturbance sites, soil is highly vulnerable to erosion by wind and water. Eroded soil endangers water resources by reducing water quality and causing the siltation of aquatic habitat for fish and other desirable species. Deposits of eroded soil also necessitate maintenance of sewers and ditches and the dredging of lakes. In addition, clearing and grading during construction cause the loss of native vegetation necessary for terrestrial and aquatic habitat. Construction activities also utilize materials and generate wastes, which if not properly controlled can pollute receiving waters.
101.3 Purpose: The purpose of this Code is to safeguard persons, protect property and prevent damage to the environment in St. Louis County. This Code will also promote the public welfare by guiding, regulating and controlling the design, construction, use and maintenance of any development or other activity that disturbs or breaks the topsoil or results in the movement of earth on land in St. Louis County.
101.4 Scope: This Code provides for the safety, health and welfare of the public by regulating and controlling the design, construction, use and maintenance of any development or other activity that disturbs land surfaces or results in the movement of earth in the unincorporated part of St. Louis County, Missouri.

7. Phasing shall be required on all sites disturbing greater than thirty (30) acres of land. The size of each phase will be established by the Department of Planning at the time of plan review for the issuance of a major Land Disturbance Permit.
201.2 Erosion Control Design: Erosion control requirements shall include the following:
1. Soil stabilization shall be completed within five (5) days of clearing or inactivity in construction.
2. If seeding or another vegetative erosion control method is used, it shall become established within two (2) weeks or the site shall be re-seeded or a non-vegetative option employed.
3. Techniques shall be employed to ensure stabilization on steep slopes and in drainage ways.
4. Soil stockpiles must be stabilized or covered at the end of each workday or perimeter controls must be in place to prevent silt from the stockpile from leaving the site.
5. The entire site must be stabilized, using a heavy mulch layer or another method that does not require germination to control erosion, at the close of the construction season.
6. Techniques shall be employed to prevent the blowing of dust or sediment from the site.
7. Techniques shall be employed to divert upland runoff past disturbed slopes.
201.3 Sediment Control Design: Sediment control requirements shall include:
1. Settling basins, sediment traps or tanks and perimeter controls.
2. Settling basins shall be provided for each drainage area within ten (10) or more acres disturbed at one time and shall be sized to contain one-half (0.5) inch of sediment from the drainage area and be able to contain a 2-year, 24-hour storm. If the provision of a basin of this size is impractical, other similarly effective Best Management Practices (BMP), as evaluated and specified in the Stormwater Pollution Prevention Plan (SWPPP), shall be provided.
3. Settling basins shall be designed in a manner that allows adaptation to provide long-term stormwater management, as required by the County Department(s) having enforcement authority and responsibilities described in Section 103.0 of this Code.
4. Settling basins shall have stabilized spillways to minimize the potential for erosion of the spillway or basin embankment.
5. Protection for adjacent properties by the use of a vegetated buffer strip in combination with perimeter controls.
201.4 Watercourse Design: Watercourse protection requirements shall include:
1. Encroachment into or crossings of active watercourses/riparian areas and wetlands shall be avoided to the maximum extent practicable. All County, State and Federal permits and approvals shall be obtained by a permit holder prior to beginning work authorized by a County Land Disturbance Permit.
2. Stabilization of any watercourse channels before, during and after any in-channel work.
3. If a defined watercourse is to be re-aligned or re-configured, clearing and grubbing activities within fifty (50) feet of the watercourse shall not begin until all materials and equipment necessary to protect the watercourse and complete the work are on site. Once started, work shall be completed as soon as possible. Areas within fifty (50) feet of the watercourse shall be re-contoured and re-vegetated, seeded or otherwise protected within five (5) working days after Land Disturbance Activities have ceased.
4. All stormwater conveyances shall be designed according to the criteria of the St. Louis Metropolitan Sewer District (MSD) and the necessary MSD permits obtained.
5. Stabilization adequate to prevent erosion shall be provided at the outlets of all pipes and paved channels.
201.5 Construction Site Access Design: Construction site access requirements for major Land Disturbance Activities shall include:
1. A temporary access road provided at all land disturbance sites including a wash down area supporting all active sites.
2. The Department of Highways and Traffic may require other measures to ensure that construction vehicles do not track sediment onto public streets or be washed with wash effluent channeled directly into storm drains.
201.6 Control of Construction Materials and Waste: Control requirements for construction materials, construction wastes and other wastes generated on site at land disturbance sites shall include provisions satisfactory to the County Department(s) having enforcement authority and responsibilities described in Section 103.0 of this Code for:
1. Spill prevention and control facilities for materials such as paint, solvents, petroleum products, chemicals, toxic or hazardous substances, substances regulated under the Resource Conservation and Recovery Act (RCRA) or the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) and any wastes generated from the use of such materials and substances, including their containers. Any containment systems employed to meet this requirement shall be constructed of materials compatible with the substances contained and shall be adequate to protect both surface and ground water.
2. Collection and disposal of discarded building materials and other construction site wastes, including those listed in Section 201.6.1 above.
3. Litter control.
4. Control of concrete truck washouts.
5. Assurance that on-site fueling facilities will adhere to applicable Federal and State regulations concerning storage and dispensers.
6. Provision of sufficient temporary toilet facilities to serve the number of workers on major Land Disturbance sites.

SECTION 301.0 GENERAL
301.1 Department of Public Works — General: The County Department(s) having enforcement authority and responsibilities described in Section 103.0 of this Code shall make inspections as herein required and shall either approve that portion of the work completed or shall notify the permit holder wherein the work fails to comply with the Land Disturbance, Erosion and Sediment Control Plan as approved. Plans for land disturbance, stripping, excavating and filling work bearing the stamp of approval of the County Department issuing the permit shall be maintained at the site during the progress of the work. To obtain inspections, a permit holder shall notify the Department of Public Works at least two (2) working days before the following:
1. Start of construction
2. Installation of sediment and erosion measures
3. Completion of site clearing
4. Completion of rough grading
5. Completion of final grading
6. Close of the construction season
7. Completion of final landscaping
Exception: Inspections conducted by the Department of Highways and Traffic related to construction and maintenance of County highways and roadways.
301.1.1 Extra Inspections: In addition to the inspections otherwise required, the Department of Public Works is authorized to perform and charge fees for extra inspections or re-inspections which in their judgment are reasonably necessary due to non-compliance with the requirements of this Code or work not ready or accessible for inspection when requested.
301.2 Permit Holder Inspection and Report Responsibilities — Major Land Disturbances: The holder of a major Land Disturbance Permit or his/her agent shall cause regular inspections of land disturbance sites, including all erosion and sediment and other pollutant control measures, outfalls and off-site receiving waters in accordance with the inspection schedule outlined in the approved Stormwater Pollution Prevention Plan (SWPPP). Inspections must be scheduled at least once per week and no later than seventy-two (72) hours after heavy rain. The purpose of such inspections will be to ensure proper installation, operation and maintenance of Best Management Practices (BMP) and to determine the overall effectiveness of the Stormwater Pollution Prevention Plan (SWPPP) and the need for additional control measures. All inspections shall be documented in written form on weekly reports with copies submitted to the Department of Public Works at the time interval specified in the permit.
