[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.
