1. Applicant's NPDES general permit #2 NOI and authorization letter.
2. The site specific stormwater pollution prevention plan (SWPPP) utilizing the city checklist for such plans available at the public works department.
3. Applicant's plans, specifications, and supporting data, if not already part of the NOI submittal, to include any information regarding concentrations of stormwater pollutants, if known, and not already required to be submitted.
4. Completed COSESCO permit application with applicable fees.
B. Every SWPPP submitted to the city in support of an application for a COSESCO permit shall have the following:
1. An SWPPP shall be a separate document from the engineered construction plans that complies with all current minimum mandatory requirements for SWPPPs promulgated by the IDNR in connection with issuance of an NPDES general permit #2.
2. A statement confirming that the plan complies with the minimum mandatory requirements of the joint application form, "Protecting Iowa Waters", Iowa department of natural resources, and the U.S. army corps of engineers.
3. A signed and dated certification by the person preparing the SWPPP, that the plan complies with all other applicable state or federal permit requirements in existence at the time of application and all requirements of this chapter.
C. In addition to the SWPPP requirements stated above, which constitute minimum mandatory requirements imposed by the program, every SWPPP submitted to the city in support of an application for a COSESCO permit shall comply with the "Statewide Urban And Design Specifications Design Manual" for design, location, and phased implementation of effective, practicable stormwater pollution prevention measures, and shall also:
1. Assure that stockpiled soil or other materials subject to erosion by wind or water are covered, vegetated, or otherwise effectively protected from erosion and sedimentation in accordance with the amount of time the material will be on site and the manner of its proposed use; no stockpiling is allowed in the street.
2. Identify measures and procedures to reasonably minimize site soil compaction.
3. Assure that all temporary erosion and sediment control measures shall not be removed until the site has been permanently stabilized.
4. Assure that all disturbed sites be permanently stabilized with seventy percent (70%) perennial cover as defined by the U.S. EPA NPDES general permit.
5. Identify methods to prevent sediment damage to adjacent properties and sensitive environmental areas.
6. Provide for design and construction methods to stabilize steep or long continuous slopes.
7. Protect storm sewer infrastructure from sediment loading/plugging.
8. Specify precautions to be taken to contain sediment when working in or crossing water bodies and streets.
9. Provide for proper disposal of collected sediment and floating debris.
D. For the duration of the time that the construction site is subject to the NPDES general permit #2 and the COSESCO permit, the applicant shall provide to the city, and keep current, the following:
1. The name, address, and telephone number of the person designated by the applicant who is knowledgeable and experienced in erosion and sediment control and who will oversee compliance with the NPDES general permit #2 and the COSESCO permit.
2. The name, address, and telephone number of the individual or firm responsible for the installation and maintenance of each erosion and sediment control measure identified in the SWPPP.
Applicant's failure to provide current information shall constitute a violation of this chapter.
E. If the applicant for the NPDES general permit #2 and the COSESCO permit is not the same individual as the owner/builder on the site, then the applicant has the option to include the owner/builder as a copermittee. Copermittees have the same obligations and responsibilities as the original applicant. Absent written confirmation of transfer of responsibility signed by both the parties and provided to the city at the office of the enforcement official, the original applicant remains obligated and responsible for permit compliance on any parcel of the site, whether the parcel has been sold or not.
F. Upon receipt of an application for a COSESCO permit, the city shall either find that the application complies with this chapter and issue a city COSESCO permit in accordance with this chapter, or that the application fails to comply with this chapter, in which case the city shall provide a written report identifying noncompliant elements of the application.
