The regulations are being administered through EPA's National Pollutant Discharge Elimination System (NPDES) permit program. The regulations specifically identified the City of Miami as a large (population over 250,000) municipality ("municipal separate storm sewer system") required to submit a municipal permit application. The permit application is submitted in two parts. On August 9, 1991, the City of Miami contracted CH2M HILL to provide professional services associated with the preparation of the Part I permit application. That work was successfully completed and the Part I permit application submitted by the EPA designated deadline. This document outlines the scope of services associated with the Part II NPDES permit application process for the City of Miami. The scope of services was developed for the purpose of meeting the minimum requirements of the regulations. The scope of services is organized into the following sections: • Introduction • Objectives • Scope of Work • Assumptions • Support to be Provided by the CITY • Cost and Schedule of Deliverables 100100C4.DFB 1 Regulatory Deadlines The municipal permit application is to be submitted in two parts. For the City of Miami, Part I of the municipal permit application was submitted to the EPA by the designated deadline (November 18, 1991). Part II is due by November 16, 1992. Part I was intended to provide background information for identifying potential sources of pollutants in storm water. Part II is intended to supplement the information obtained under Part I and develop a comprehensive storm water quality management program to control pollutants to the "maximum extent practicable." Permitting Process Each permit application will be reviewed for completeness by the EPA, and the City will be notified of the review outcome in writing. If incomplete, the EPA will issue a "Notice of Deficiency" listing the information necessary and specifying a submittal date. The effective date of an application is the date when the permitting authority determines that the application is complete. Upon review of an application, the EPA will either issue a draft permit or a notice to deny the permit, including a statement of basis or a draft fact sheet. All draft permits and notices of intent to deny a permit are subject to public review and will be made available for public comment. The EPA will make a final permit decision after the close of the public comment period. The final permit will specify the effective date of the permit, at which time the City is legally authorized to discharge storm water, subject to the permit conditions. NPDES permits for storm water discharge will be issued by the EPA Region IV Office for a period up to, but no longer than 5 years. At any time during that period, the City may file a request for permit modification, reissuance, or a notification of planned changes. Objectives The objective of this project is for CH2M HILL to provide the services associated with the NPDES permitting process for the City of Miami, which include the following: Phase Description 1 Permit Preparation and Submittal 2 Negotiations and Submittal of Additional Information dbt 118/051.51 2 This document outlines CH2M HILL's scope of services for completion of Phase 1 of the permit process, which includes planning, preparing, and submitting Part II of the municipal permit application for the purpose of meeting the requirements of the NPDES regulations as mandated by the Environmental Regulatory Agency. Previously, CH2M HILL completed Part I of the permit application under Phase 1 of this project, and submitted the required documents by the EPA designated deadline. The project permit area includes the CITY limits. The scope of services, cost, and schedule for Phase 2 of the NPDES permit process are difficult to estimate at this time and will developed at a later time in response to specific regulatory requirements. Scope of Work Part II of the application is intended to supplement the information provided in Part I, and develop a comprehensive storm water quality management program to control the discharge of pollutants from storm sewers to the "maximum extent practicable". As mandated in the regulations, the Part II application must address the following: • Demonstration of adequate legal authority for the CITY to control the discharge of pollutants to the municipal storm sewer system • Complete inventory of "major" outfalls discharging to "waters of the U.S.", and identification of industrial facilities with potential to discharge into the storm sewer system • Sampling and analysis of runoff water quality for representative land uses, calculation of runoff pollutant loads to waters of the U.S, and development of a runoff monitoring program for the life of the permit • Development of a management program to control pollutant discharges to the "maximum extent practicable", including identification and rank- ing of structural and source controls, development of a maintenance and operation program, identification of staff resources needed for program implementation, intergovernmental coordination, and public information. • Estimates of the pollutant reduction projected for stormwater controls proposed for implementation during the life of the permit • Development of cost estimates associated with the implementation of the management program, including a fiscal analysis of annual dbt118/051.51 3 expenditures for the life of the permit. The fiscal analysis must address capital expenditures, operation and maintenance costs, source of funds, and a description of the legal restrictions on the use of such funds The, scope of work was organized into the same tasks listed in the regulations to facilitate review by City staff and cross-reference with the regulations. To complete Part II of the municipal permit application, CH2M HILL will perform the following tasks: Task Description A Legal Authority B Source Identification C Characterization Data D Proposed Management Programs E Assessment of Controls F Fiscal Analysis G Roles and Responsibilities H Part II Permit Application A. Legal Authority The regulations require that adequate legal authority be demonstrated by the City of Miami to control discharges to the municipal storm sewer system. On the Part I permit application, the City took the position that existing legal authority is sufficient and that no additional authority was necessary. On that basis, no services will be provided in association with this task. It must be noted, however, that the EPA may require additional authorities to be developed pending the results of their review of the City of Miami Part I permit application. B. Source Identification CH2M HILL will complete the following activities to provide the required information under this task: 1. Develop GIS overlay map showing up to 400 drainage basins within CITY limits. Map overlay will be obtained from Dade County DERM. Work for this overlay will be limited to the following: a. Review DERM overlay with CITY staff b. Correct up to 100 basin boundaries based on CITY input dbt 118/051.51 4 4k C. Adapt overlay to CITY street base map developed under Part I permit application. No field work will be conducted in association with this task 2. Develop storm sewer system map. The GIS street map developed under Part I will serve as the base map, and the existing City Drainage Atlas Maps will be used as the source of information for the storm sewer system. The following storm sewer system information will be inventoried into separate layers: a. Sewer lines b. Manholes C. Inlets d. Exfiltration trenches e. Pump stations f. Drainage wells g. Catch basins CITY will be responsible for providing updated Drainage Atlas Sheets and attribute information (characteristics) for each element of the storm sewer system to be included in the GIS database No field work will be conducted in association with this task 3. Develop GIS overlay map showing the locations of facilities which may discharge storm water associated with industrial activity (as defined under 40 CFR Part 122.26(b)(14) of the NPDES regulations) into the municipal storm sewer system Prepare an inventory, organized by watershed, of the name, address, and SIC code of each facility identified. The inventory information will be extracted from standard industry listings, such as the Florida Chamber of Commerce's Directory of Florida Industries, and the Florida Manufacturers' Directory, as well as information provided by CITY staff. 4. Relate GIS maps/overlays to information in the relational data base, conduct the necessary analysis, and produce the following system inventory reports: a. Summary report for each water body designated "waters of the U.S.", showing the following: dbt118/051.51 • Total drainage area (acres) 5 • Total number and list of contributing drainage basins (by basin ID) • Total number of "major" and "minor" outfalls discharging to "waters of the U.S." 1,1 • Percent of each land use category for entire drainage area dbt 118/051.51 • Drainage area composite runoff factor • Total number and list of landfills • Total number and list of NPDES permitted dischargers (by permittee ID number) • Total number and list of industrial facilities identified under Task B.3 above • Total number of stormwater structural controls for the following categories of controls: - Drainage wells - Pump stations - Exfiltration trenches - Storm sewer pipes For each of the first three categories, list the combined capacity in acre-ft/yr. For the storm sewer pipes, list the total pipe length for pipe size ranges designated by CITY • Total area of public lands (acres), percent of total drainage area, and total number of parcels b. Report the following information for each contributing basin on the drainage divide overlay: • Drainage basin identification number • Drainage area (acres) • List of publicly owned lands showing area (acres) and percent of drainage area for each parcel, as well as totals 0 a dbt 118/051.51 • List of "major" and "minor" outfalls discharging to "waters of the U.S.". including pipe ID number and dimensions • List of outfalls discharging across basin boundaries into other basins, including pipe ID number and dimensions • Percent of each land use category • Basin composite runoff factor • List of landfills • List of NPDES permitted dischargers, including name, address, and number of each permittee • List of industrial facilities identified under Task B.3 above, including name, address, and SIC codes • List of stormwater structural controls, including ID number, dimensions (diameter, length), and capacity for the following categories of controls: - Drainage wells - Pump stations - Exfiltration trenches - Storm sewer pipes For the storm sewer pipes, list the total pipe length for pipe size ranges designated by CITY • List publicly owned lands, including area (acres), owner's name, and address Drainage basin information will be grouped by "waters of the U.S.", and sorted by drainage basin ID in increasing order of magnitude C. List of "major" and "minor" outfalls and summary of outfall information grouped by "waters of the U.S.", and sorted by drainage basin ID in increasing order of magnitude, and increasing order of outfall ID 7 i"� 5. Plot hard copies of the base map and each overlay map at a scale which results in no more than two standard 2' x 3' sheets per map. One draft and one final copy of each of the maps will be prepared 6. Provide files and assist in the transfer of electronic files of maps and data base to the GIS computer system of the City's Planning Department. Assistance will not exceed 40 man-hours 7. Attend three coordination meetings with the City 8. Prepare memorandum TM2.13, "Source Identification", summarizing the information compiled and presenting tables and GIS maps. A single - draft memorandum will be prepared and five copies submitted for review by the CITY. CITY comments will be incorporated into the ^; draft Part II Permit Application (Task H) C. Characterization Data CH2M HILL will complete the following activities to provide the required information under this task: 1. Quantitative runoff data will be collected from up to five representative locations. For each site, up to three representative storm events, at least 1 month apart, and greater than 0.1 inches, will be monitored. Storm events will only be monitored if preceded by 72 hours of dry - weather since the last measurable storm (> 0.1 inches). A maximum of 15 storm events will be monitored. Data to be collected during each storm event includes: a. Date and duration of storm b. Time since last storm of more than 0.1 inches as recorded at the nearest existing hourly rainfall station C. Hourly rainfall for the first 3 hours of the storm (maximum of four readings per storm). Rainfall data will be obtained from an existing nearby station or bulk rainfall measuring device d. Hourly flow estimates for the first 3 hours of the storm (maximum of four estimates per storm). If practical, flow estimates will be based on hourly velocity measurements. Otherwise, flows will be estimated as the product of hourly rainfall, drainage area, and basin runoff factor dbt118/051.51 '% '41) Q� e. A single grab sample will be obtained within the first hour of the storm event and analyzed for: • pH • temperature • cyanide • total phenol • oil and grease • fecal coliform • fecal streptococcus f. A single flow -composite sample will be prepared by flow - weighing up to four grab samples obtained during the first three hours of the storm. Flow -weighing will be based on the flow estimates generated above. The composite sample will be analyzed for the Table 1 parameters labeled composite Since samples for volatile organic compounds cannot be collected with the aid of an automatic water quality sampler, it was assumed that all samples will be collected manually (grab samples). 2. Enter data collected above into a computer database and analyze the information as follows: a. Provide statistical summary of data (number of samples, mean, standard deviation, range, outliers) dbt 118/051.51 b. Obtain similar data for Dade County and Hialeah, summarize, and compare with data collected in Miami C. Compare EMCs with state and local water quality standards and identify constituents and sites exceeding standards d. Relate event mean concentrations (EMCs) to land use data and identify any relationships using regression analysis e.

Roles and Responsibilities When more than one legal entity is involved in the permit application (co -applicants), the EPA requires a description of the roles and responsibilities of each legal entity, and procedures to ensure effective coordination. It was assumed that this task does not apply to the CITY and, therefore, no work will be performed under this task H. Part II Permit Application CH2M HILL will complete the following activities to provide the required information under this task: 1. Revise all technical memoranda according to review comments received from the CITY and reorganize documents to accommodate final application format 2. Prepare one draft Part II Municipal Permit Application and submit five copies for CITY staff review 3. Revise draft Part II application based on review comments received from the CITY, conduct final editorial review, prepare final Part II application, and submit ten copies to the City 4. Attend one application review meeting with the City 5. Attend one application review meeting with the EPA Assumptions In the absence of an EPA guidance manual for preparation of Part II of the permit application, the scope of services was developed on the basis of CH2M HILL's cur- rent interpretation of the regulations, our past experience, and consultation with EPA personnel. At present, it cannot be determined when the EPA intends to publish such guidance manual for Part II. Even if the Part II guidance were available, there is no guarantee that the EPA will not change its interpretation of the regulatory requirements. For example, the guid- ance manual for Part I of the permit application noted that the EPA reserves the right to revise guidance criteria at any time. dbt 118/051.51 21 The scope of work was designed to cost-effectively provide the information required by the EPA within the designated deadlines, expedite negotiations with the EPA, and facilitate approval of the required permit. However, due to factors outside of CH2M HILL's control, the company cannot predict the level of effort and duration of the negotiations with the EPA, nor guarantee meeting the deadlines or obtaining permit approval. Factors outside of CH2M HILL's control include the project starting date (issuance of notice to proceed), inadequate sampling weather conditions, and changes in EPA's guidance criteria and interpretation of the regulations. The scope of work includes all tasks up to submittal of the permit application, and does not include permit negotiations with the EPA, nor any additional work that may be required to satisfy EPA's request for additional information following submittal of the application. Support to be Provided by the City Following is a summary of the support needed from the City to successfully complete this project. Most of the City's assistance will be required to identify and provide existing information about the City. CH2M HILL will meet with the designated City staff to obtain the required information. In addition to the assistance and work efforts indicated in the scope of work, the City will provide the following support at no cost to CH2M HILL: • Attend meetings • Provide information as needed • Provide copies of all previous studies, maps, data, and reports on storm water • Review draft deliverables --A single draft will be prepared for review by City staff. The City will consolidate all review comments into a single document and transmit to CH2M HILL with a cover memorandum from the City's project manager. The City agrees that its review com- ments will be delivered to CH2M HILL's Miami Office within 14 calen- dar days following receipt of the draft document(s) from CH2M HILL Cost and Schedule of Deliverables Table 2 summarizes the cost and schedule of deliverables for this project. The table shows the costs to CH2M HILL as well as the costs to the CITY associated with each 100100CD.DFB 22 deliverable. The schedule of deliverables assumes that the project is authorized by no later than February 3, 1992. Otherwise, the schedule will have to be adjusted to reflect a late start. CH2M HILL will submit monthly invoices to the CITY based on the estimated percent complete for all work conducted to date, up to the authorized lump sum, less previous payments made by the CITY. 100100CD.DFB 23 6 CITY OF MIAMI.

I,;C, a2- � r The City Commission designated the "National Pollutant Discharge Elimination System Permit" as a Category "B" project by Resolution No. 91-121 on February 14, 1991. The City Commission approved the selection of CH2M Hill Southeast, Inc. and directed the City Manager to execute an agreement for Part I by the adoption of Resolution No. 91-579 on July 25, 1991 after a consultant selection process conforming to State and City requirements. The original agreement did not include fully developed information on or compensation amounts for the NPDES Permit Application Part II due to the late release of specific requirements from the EPA and its dependence on results from the NPDES Permit Application Part I. The amendment of the agreement is necessary at this time in order to comply with the EPA deadline of November 16, 1992 for the NPDES Part II Permit Application. The additional funds required for the increase in compensation will be allocated from the funds previously appropriated from project no. 352277 of the Capital Improvement Projects Appropriations Ordinance no. 10938. The attached cost comparison and condensed work descriptions are provided for further background. - 2 - a _4 SUMMARY SHEET _I NPDES PART 2 PERMITTING CITY OF MIAMI REGULATORY BACKGROUND On November 16, 1990, the Environmental Protection Agency (EPA) issued new regulations to control the discharge of storm water pollutants to waters of the U.S. (Federal Register, Vol. 55, No. 222, pages 47989-48091).
