[Ord. No. 2010-1621 §1, 4-20-2010]
Applications for land disturbance permits required by this Article shall be in the form prescribed by and accompanied by the site plans and documents determined necessary by the City.
[Ord. No. 2010-1621 §1, 4-20-2010]
All applications for major land disturbance permits shall be accompanied by a stormwater pollution prevention plan prepared for the specific site by or under the direction of a qualified professional. The application shall contain a statement that any land clearing, construction, or development involving the movement of earth shall be in accordance with the stormwater pollution prevention plan, and the applicant will assume and acknowledge responsibility for compliance with this Code and the stormwater pollution prevention plan at the site of the permitted activity.
[Ord. No. 2010-1621 §1, 4-20-2010]
A. 
Content — Stormwater Pollution Prevention Plan (SWPPP). The design requirements of this Article shall be complied with when developing the stormwater pollution prevention plan and the plan shall include the following:
1. 
Name, address and telephone number of the site owner and the name, address and telephone number of the individual who will be in overall responsible charge of construction/development activities at the site.
2. 
Site address or location description and parcel identification number(s).
3. 
A site map showing the outlines of the total project area, the areas to be disturbed, existing land uses, locations and names of surface water bodies, locations of flood plains, locations of temporary and permanent Best Management Practices (BMP) and such other information as may be required by the City.
4. 
Existing contours of the site and adjoining strips of off-site property and proposed contours after completion of the proposed land disturbance and development, based on United States Geological Survey datum, with established elevations at buildings, walks, drives, street and roads; and information on necessary clearing and grubbing, removal of existing structures, excavating, filling, spreading and compacting.
5. 
A natural resources map identifying soils, forest cover, and resources protected under other provisions of City ordinances.
6. 
An estimate of the runoff coefficient of the site prior to disturbance and the runoff coefficient after the construction addressed in the permit application is completed.
7. 
Estimated quantity of land to be disturbed.
8. 
Details of the site drainage pattern both before and after major land disturbance activities.
9. 
Access to construction site.
10. 
Description of Best Management Practices (BMP) to be utilized to control erosion and sedimentation during the period of land disturbance.
11. 
Description of Best Management Practices (BMP) to be utilized to prevent other potential pollutants such as construction wastes, toxic or hazardous substances, petroleum products, pesticides, herbicides, site litter, sanitary wastes and other pollutants from entering the natural drainage ways during the period of construction and land disturbance.
12. 
Description of Best Management Practices (BMP) that will be installed during land disturbance to control pollutants in stormwater discharges that will occur after land disturbance activity has been completed.
13. 
Location of temporary off-street parking, and wash-down area for related vehicles.
14. 
Sources of off-site borrow material or spoil sites, and all information relative to haul routes, trucks and equipment.
15. 
The anticipated sequence of construction and land disturbance activities, including installation of Best Management Practices (BMP), removal of temporary Best Management Practices (BMP), stripping and clearing; rough grading; construction utilities, infrastructure and buildings; and final grading and landscaping. Sequencing shall identify the expected date(s) on which clearing will begin, the estimated duration of exposure of cleared areas, areas of installation of temporary erosion and sediment control measures, and establishment of permanent vegetation.
16. 
All erosion and sediment control measures necessary to meet the objectives of this Article throughout all phases of construction and after completion of site development. Depending upon the complexity of the project, the drafting of intermediate plans may be required at the close of each season.
17. 
Seeding mixtures and rates, types of sod, method of seedbed preparation, expected seeding dates, type and rate of lime and fertilizer application, and kind and quantity of mulching for both temporary and permanent vegetative control measures.
18. 
Provisions for maintenance of control facilities, including easements and estimates of the cost of maintenance.
19. 
Plans for responding to any loss of contained sediment to include the immediate actions the permit holder will take in case of a containment failure. This plan must include documentation of actions and mandatory reporting to the City.
20. 
Schedules and procedures for routine inspections of any structures provided to prevent pollution of stormwater or to remove pollutants from stormwater and of the site in general to ensure all Best Management Practices (BMP) are continually implemented and are effective.
B. 
Required Plan Amendments — Stormwater Pollution Prevention Plan (SWPPP). The permit holder shall amend the stormwater pollution prevention plan whenever:
1. 
Design, operation or maintenance of Best Management Practices (BMP) is changed;
2. 
Design of the construction project is changed that could significantly affect the quality of the stormwater discharges;
3. 
Site operator's inspections indicate deficiencies in the stormwater pollution prevention plan (SWPPP) or any Best Management Practices (BMP);
4. 
Inspections by City or by the Missouri Department of Natural resources indicate deficiencies in the stormwater pollution prevention plan (SWPPP) or any Best Management Practices (BMP);
5. 
The stormwater pollution prevention plan (SWPPP) is determined to be ineffective in significantly minimizing or controlling erosion or excessive sediment deposits in streams or lakes;
6. 
The stormwater pollution prevention plan (SWPPP) is determined to be ineffective in preventing pollution of waterways from construction wastes, chemicals, fueling facilities, concrete truck washouts, toxic or hazardous materials, site litter or other substances or wastes likely to have an adverse impact on water quality;
7. 
Total settleable solids from a stormwater outfall exceeds 0.5 ml/L/hr if the discharge is within the prescribed proximity of a "valuable resource water" as defined by the Missouri Department of Natural Resources;
8. 
Total settleable solids from a stormwater outfall exceeds 2.5 ml/L/hr for any other outfall; or
9. 
The City or the Missouri Department of Natural Resources determines violations of water quality standards may occur or have occurred.
C. 
Permit Holder Responsibilities For Administration For Stormwater Pollution Prevention Plan (SWPPP). The permit holder shall:
1. 
Notify all contractors and other entities (including utility crews or their agents) that will perform work at the site of the existence of the stormwater pollution prevention plan (SWPPP) and what actions or precautions shall be taken while on site to minimize the potential for erosion and the potential for damaging any Best Management Practices (BMP);
2. 
Determine the need for and establish training programs to ensure that all site workers have been trained, at a minimum, in erosion control, material handling and storage, and housekeeping;
3. 
Provide copies of the stormwater pollution prevention plan (SWPPP) to all parties who are responsible for installation, operation or maintenance of any Best Management Practices (BMP); and
4. 
Maintain a current copy of the stormwater pollution prevention plan (SWPPP) on the site at all times.
