How does your business currently inform applicants, employees, and recruitment sources (including unions) that you are an Equal Employment Opportunity employer? The above responses to questions 1 through 6, are true and correctly reflect our Equal Employment Opportunity policies. Business Name Phone Number Signature Print Name Title 112327 -1 CC -3 SECTION III - SUGGESTED STEPS TO ASSURE EQUAL EMPLOYMENT OPPORTUNITIES COMPANY POLICY Determine your company's policy regarding equal employment opportunities. Document the policy and post it in a conspicuous place so that it is known to all your employees. Furthermore, disseminate the policy to all potential sources of employees and to your subcontractors asking their cooperation. The policy statement should recognize and accept your responsibility to provide equal employment opportunity in all your employment practices. In regard to dissemination of this policy, this can be done, for example, through the use of letters to all recruitment sources and subcontractors, personal contacts, employee meetings, web page postings, employee handbooks, and advertising. 2. EQUAL EMPLOYMENT OPPORTUNITY OFFICER Designate an equal employment opportunity officer or, at minimum, assign someone the responsibility of administering and promoting your company's Equal Employment Opportunity program. This person should have a position in your organization which emphasizes the importance of the program. 3. INSTRUCT STAFF Your staff should be aware of and be required to abide by your Equal Employment Opportunity program. All employees authorized to hire, supervise, promote, or discharge employees or are involved in such actions should be trained and required to comply with your policy and the current equal employment opportunity laws. 4. RECRUITMENT (a) Let potential employees know you are an equal opportunity employer. This can be done by identifying yourself on all recruitment advertising as "an equal opportunity employer'. (b) Use recruitment sources that are likely to yield diverse applicant pools. Word -of -mouth recruitment will only perpetuate the current composition of your workforce. Send recruitment sources a letter annually which reaffirms your commitment to equal employment opportunity and requests their assistance in helping you reach diverse applicant pools. (c) Analyze and review your company's recruitment procedures to identify and eliminate discriminatory barriers. (d) Select and train persons involved in the employment process to use objective standards and to support equal employment opportunity goals. (e) Review periodically job descriptions to make sure they accurately reflect major job functions. Review education and experience requirements to make sure they accurately reflect the requirements for successful job performance. (f) Review the job application to insure that only job related questions are asked. Ask yourself "is this information necessary to judge an applicant's ability to perform the job applied for ?" Only use job - related tests which do not adversely affect any particular group of people. (g) Monitor interviews carefully. Prepare interview questions in advance to assure that they are only job related. Train your interviewers on discrimination laws. Biased and subjective judgments in personal interviews can be a major source of discrimination. (h) Improve hiring and selection procedures and use non - biased promotion, transfer and training policies to increase and /or improve the diversity of your workforce representation. Companies must make sure procedures for selecting candidates for promotion, transfer and training are based upon a fair assessment of an employee's ability and work record. Furthermore, all companies should post and otherwise publicize all job promotional opportunities and encourage all qualified employees to bid on them. 112327 -1 CC -4 " o T1 ® City of VVA %0 % Attached for your information is a copy of Section 2 — 3 — 1 of the Iowa City Code of Ordinances which prohibits certain discriminatory practices in employment.

Amendments to the plan may be reviewed by the Department of Natural Resources in the same manner as Part W.B.2. D. CONTENTS OF THE POLLUTION PREVENTION PLAN. The storm water pollution prevention plan shall include the following items: 1. SITE DESCRIPTION Each plan shall provide a description of the following: A. a description of the nature of the construction activity; B. estimates of the total area of the site and the area of the site that is expected to be disturbed by excavation, grading, or other activities; C. an estimate of the runoff coefficient of the site after construction activities are completed and existing data describing the soil or the quality of any discharge from the site; D. a site map indicating drainage patterns and approximate slopes anticipated after major grading activities, areas of soil disturbance, the location of structural and nonstructural controls identified in the plan, the location of areas where stabilization Practices are expected to occur, surface waters (including 'wetlands), and locations where storm water is discharged to a surface water; and ,E.; the name of the receiving water(s) and the ultimate receiving water(s). EFFECTIVE DATE -OCTOBER 1, 2012 TO OCTOBER 1, 2017 2. CONTROLS Each plan shall include a description of controls that will be implemented at the construction site. The plan will clearly describe the intended sequence of major activities and for each activity, the appropriate control measures and the timing during the construction process that the measures will be implemented. (For example, perimeter controls for one portion of the site will be installed after the clearing and grubbing necessary for installation of the measure, but before the clearing and grubbing for the remaining portions of the site. Perimeter controls will be actively maintained until final stabilization of those portions of the site upward of the perimeter control. Temporary perimeter controls will be removed after final stabilization). The description of controls shall address the following mininmm components: A. EROSION AND SEDIMENT CONTROLS A.(1). STABILIZATION PRACTICES A description of temporary and permanent stabilization practices, including site - specific scheduling of the implementation of the practices. Site plans should ensure that existing vegetation is preserved where attainable and that disturbed areas are stabilized. Stabilization practices may include: temporary seeding, permanent seeding, mulching, geotextiles, sod stabilization, vegetative buffer strips, protection of trees, preservation of mature vegetation, and other appropriate measures. Except as precluded by snow cover, stabilization measures shall be initiated on all disturbed areas as soon as practical but in no case where construction activity will not occur for a period of 21 or more calendar days later than the 14th day after no construction activity has occurred on such area. Where the initiation of stabilization measures by the 14th day after no construction activity occurs is precluded by snow cover, then stabilization measures shall be initiated as soon as practicable thereafter. A.(2). STIIUCTURAL PRACTICES A description of structural practices to the degree attainable, to divert flows from Io %vA DEPARTMENT OF NATURAL. RESOURCES NPDF.S GENERAL. PERNIFF No.2 STORM WATER DISCHARGE ASSOCIATED WITH INDUSTRIAL ACTlvnv FOR CONSTRUCTION ACTIVITIES exposed soils, store flows or otherwise limit runoff from exposed areas of the site. Such practices may include silt fences, earth dikes, brush barriers, drainage swales, sediment traps, check dams, subsurface drains, pipe slope drains, level spreaders, storm drain inlet protection, rock outlet protection, reinforced soil retaining systems, gabions, and temporary or permanent sediment basins. Structural practices should be placed on upland soils to the degree attainable. The installation of these devices may be subject to Section 404 of the CWA. A.(2).(rr). For common drainage locations that serve an area with more than 10 disturbed acres at one time, a temporary or permanent sediment basin providing 3,600 cubic feet of storage per acre drained shall be provided where attainable until final stabilization of the site has been achieved. The 3,600 cubic feet of storage area per acre drained does not apply to flows from offsite areas and flows from onsite areas that are either undisturbed or have undergone final stabilization where such flows are diverted around the sediment basin. For drainage locations which serve more than 10 disturbed acres at one time and where a temporary sediment basin providing 3,600 cubic feet of storage per acre drained is not attainable, sediment traps, silt fences, or equivalent sediment controls are required for all sideslope and downslope boundaries of the construction area. A.(2).(b). For drainage locations serving 10 or fewer acres, sediment traps, silt fences or equivalent sediment controls are required for all sideslope and downslope boundaries of the construction area or a sediment basin providing for 3,600 cubic feet of storage per acre drained. A.(2).(e). Unless infeasible, the following measures shall be implemented at all sites: utilize outlet structures that withdraw water from the surface when discharging fron basins, provide and maintain natural buffers around surface waters, direct storm water to vegetated areas to increase sediment removal and maximize storm water infiltration and minimize soil compaction. Topsoil shall be EFFECTIVE DATE -OCTOBER 1, 2012 TO OCTOBER 1, 2017 preserved at all construction sites unless land use precludes the practice. The requirement to preserve topsoil shall be met only when the depth of topsoil after soil disturbing activities have been completed and final stabilization achieved for the permitted activity is equal to, or greater than, 4.0 inches, including soil contained in sod, on all areas of the site where the surface of the ground disturbed for the permitted construction activities is exposed and not covered by concrete, asphalt, gravel or other such material and where 4.0 inches or more of topsoil existed prior to the commencement of soil disturbing activities that are permitted under the. current ,perrnit authorization for the site. Oil areas vvliere less than 4.0 inches of topsoil existed_ prior to the commencement of soil disturbing activities that are permitted under the current permit authorization for the site, the minimu_m,depth of topsoil after soil disturbing _activities have been completed and final stabilization achieved for the permitted activity shall be equal to, or greater than, tine depth of topsoil that existed prior to the commencement of soil disturbing activities that are permitted under the current permit authorization for the site. The final topsoil depth is to be measured after the soil has been compacted in a fashion generally considered adequate for an established lawn and so that the expected settling that will occur after measurement will be minimal and shall include the soil contained in any sod that has been placed on the site. The type of topsoil at the site after soil disturbing activities have been completed and final stabilization achieved for the permitted activity shalt be similar to that which exists or existed in the general area of the site.

For sites where less than 4.0 inches of topsoil is to be in place after soil disturbing activities have been completed and final stabilization achieved for the permitted activity, a soil survey conducted by properly qualified personnel who regularly conduct soil surveys as part of their normal job duties must be conducted prior to commencement of soil disturbing activities that are permitted under the current permit authorization for the site. The results of the soil survey shall become part of the Pollution Prevention Plan and shall indicate the depth of topsoil at a suitable number of points on the site commensurate with standard engineering practices established for the size of the site. The topsoil preservation requirement described above shall be implemented for projects that have not received an authorization under this permit prior to October 1, 2012. The topsoil preservation requirements are not required to be implemented for projects that have been authorized prior to October 1, 2012. In residential and commercial developments, a plat is considered a project. For other large areas that have been authorized for multiple construction sites, including those to be started at a future date, such as those located at industrial facilities, military installations and universities, a new construction project not yet surveyed and platted out is considered 'a - project. This stipulation is intended to be ;interpreted as requiring the topsoil preservation requirements on development plats and :construction activities on other extended` -areas that may have several construction projects permitted under the same authorization to be implemented on those projects not yet surveyed and platted out prior to October 1, 2012 even if other plats orgl construction activities in the same development or other extended area were authorized prior to October 1, 2012. R. STORM WATER MANAGEMENT A description of measures that will be installed during construction to control pollutants in EFFECTIVE DATE - OCTOBER 1, 2012 TO OCTOBER 1, 2017 storm water discharges that will occur after construction operations have been completed. The installation of these devices may be subject to Section 404 of the CWA. This permit only addresses the installation of storm water management measures, and not the ultimate operation and maintenance of such structures after the construction activities have been completed and the site has undergone final stabilization. Pernniltees are only responsible for the installation and maintenance of storm water management measures prior to final stabilization of the site, and are not responsible for maintenance after storm water discharges associated with industrial activity have been eliminated from the site. R.(1). Such practices may include: storm water detention structures (including wet ponds); storm water retention structures; flow attenuation by use of open vegetated swales and natural depressions; and infiltration of runoff unite; and sequential systems (which combine several practices). A goal of 80 percent removal of total suspended solids from those flows which exceed predevelopment levels should be used in designing and installing storm water management controls (where practicable). Where this goal is not met, the permittee shall provide justification for rejecting each practice based on site conditions. 13.(2). Velocity dissipation devices shall be placed at discharge locations and along the length of any outfall channel as necessary to provide a non- erosive velocity flow from the structure to a water course so that the natural physical and biological characteristics and functions are maintained and protected (e.g. maintenance of hydrologic conditions present prior to the initiation of construction activities).

A. General Upon completion of a newly installed water main or when repairs to an existing water system are made, the main shall be disinfected according to instructions listed in ANSI /AWWA C651 and the following specifications. B. Special Disinfection Requirements Exercise cleanliness during construction. Protect pipe interiors, fittings and valves against contamination. 2. The minimum uniform concentration of available chlorine used for disinfection shall be 50 nTg/L. Use either the granulated /tablet or continuous feed method with modifications as described in 3.11 C or D below. The chlorinated water shall be retained in the main at least 24 hours, during which time all valves and hydrants in the section treated shall be operated in order to disinfect the appurtenances. At the end of this 24 hour period, the treated water shall contain no less than 25 mg/L chlorine throughout the length of main. 4. After the retention period, flush the heavily chlorinated water from the main until the chlorine concentration in the water leaving the main is no higher than 3 nTg/L and the water appears clean. Flush at a minimum velocity of 2.5 feet per second in the main through an opening not less than '/4 of the main diameter. For 6 -inch through 12 -inch water mains, a single 2% -inch fire hydrant opening is adequate. Water entering storm sewer system shall be dechlorinated by a method approved by the Engineer to prevent downstream environmental damage (i.e. fish kills). WATER DISTRIBUTION- CITY OF IOWA CITY - 02660 02/14/11 Page 14 of 17 5. After final flushing and before the new water main is connected to the distribution system, two consecutive sets of acceptable samples, taken at least 24 homy apart, shall be collected from the new main. At least one set of samples shall be collected front every 800 -1000 feet of the new water main. plus one set from the end of the line and at least one from each branch. Deliver the sample to the University Hygienic Laboratory at Oakdale for analysis. Allow approximately 5 days for the results. If the bacterial sample shows the absence of coliform organisms, the hydrostatic test may proceed. C. Tablet Method of Chlorine Application 1. Use ANSI /AWWA C651, however slowly fill the main (less than I cubic foot per second) with system water, pushing out as much air as possible. Do not wash out the tablets. D. Continuous Feed Method of Chlorine Application 1. Prior to applying chlorine, do a preliminary flush at a minimum velocity of 2.5 feet per second in the main through an opening not less than not less than '/4 of the main diameter. For 6 -inch through 12 -inch water mains,,a,single 2' /z -inch fire hydrant opening is adequate. 2. Add the water and chlorine solution with the required concentration to fill the main completely. 3.12 TESTING. A. Filling the water main: Fill the newly constructed water main system slowly using treated public water under low pressure and low flow. The objective is to displace air with water while avoiding damage to new construction, customer services, and adjoining property due to the release of air and water. Public Works staff must be on site to assist with operation of the system valves and hydrants during this operation. 2. Open one hydrant (completely) at the end of the main or at a high point on the mail which is to be filled. Open a filling valve (the smallest one available) slightly. Allow the water main to fill and slowly release the air. When the main being filled has released nearly all air, surging should diminish and water released from the hydrant should flow in a steady stream. Monitor and control the released water to minimize damage. WATER DISTRIBUTION- CITY OF IOWA CITY - 02660 02114/11 Page 15 of V After a few minutes of steady state operation, open all other valves slowly and then open the initial fill valve completely, while regulating the flow hydrant to minimize damage. When the main has been filled, open and close all hydrants sequentially to force fresh water progressively through each section (new and old) of water main which was shut down to replace fi-esh water into each section. 4. After clear water and a fresh chlorine odor are observed at each hydrant, shut down hydrant flow slowly and allow water flow to cease and internal pressure to stabilize. For water mail replacement only, each water service connection shall be tested at a sill cock and observed by the Contractor to verify adequate pressure and flow. B. Pressure and Leakage Tests: I, Conduct combined pressure and leakage test in accordance with ANSI /AWWA C600 and ANSI /AWWA C605. 2. Pressure test off the hydrants or furnish and install temporary testing plugs or caps. Furnish pressure pumps, pipe connections, meters, gauges, equipment, potable water and labor. Use only potable water for testing. 3. Test after disinfection operations are successfully completed. If testing operations require reconstruction or repairs during which the interior of the pipe is exposed to contamination, disinfection will be required again. 4. Keep the water main full of water for 24 hours before conducting combined pressure and leakage test. 5. Pressure and leakage test consists of first raising water pressure at the lowest point of section being tested to 150 psi internal pressure. 6. Failure to achieve and maintain the specified pressure for at least two hours with no additional pumping means the water main has failed to pass the test. 7. If the water main fails the pressure and leakage test, locate, uncover, and repair or replace defective pipe, fitting orjoints. Conduct additional tests and repairs until water main passes the test. C. Valve Operations: 1. All valves shall be located and tested to verify operation. Remove the valve box lid, insert the valve key and open and close each valve. Count the turns and record the results. WATER DISTRIBUTION- CITY OF IOWA CITY - 02660 02/14111 Page 16 of 17 D. Hydrant Operations: After the hydrant has been installed and the main and hydrant have been pressure tested, each hydrant shall be flushed and checked for proper operation. 2. Remove a nozzle cap and open the hydrant slowly and fldly. Check the direction of opening as marked on the top. Do not force the hydrant in the opening direction beyond full open as indicated by sudden resistance to turning. 3. After hydrant has been flushed, close it and check for drainage. This is done by placing the hand over the nozzle opening and checking for a vacuum. Then check the hose thread for proper fit. 4. Replace nozzle cap, then open hydrant again and inspect all joints to], leaks. E. Flow Test: I. Flow tests shall be conducted to verify all components of the water system are fully open and operational and to determine the fire flow capacity. 2. Public Works staff personnel must be on the site to operate the system valves and hydrants during this test. 3. A hydrant flow test may be conducted on the hydrant at the extreme locations for distance or highest elevation to determine the fire flow capability of the system.
