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- involvgin such actions should be trained and required to comply with your policy and the current equaFerrtploy -went o p�ortunty laws. • -; s 4. RECRUITMENT (a) Let potential employees know you are an equal opportunity employe}.-'.This �cpn be_�Dbne by identifying yourself on all recruitment advertising as "an equal opportunity ernployerN (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.

The upstream or up- slope line will be inserted through both layers along a line through approximately the midpoint of the overlap. At horizontal laps and across slope laps, securing pins will be inserted through the bottom layer only. Securing pins will be placed along a line approximately 2 inches in from the edge of the placed geotextile at intervals not to exceed 12 feet unless otherwise specified. Additional pins will be installed 02270 -2 as necessary and where appropriate, to prevent slippage or movement of the geotextile. The use of securing pins will be held to the minimum necessary. Pins are to be left in place unless otherwise specified. Should the geotextile be torn or punctured, or the overlaps disturbed, as evidenced by visible damage, subgrade pumping, intrusion, or grade distortion, the backfill around the damaged or displaced area will be removed and restored to the original approved condition. The repair will consist of a patch of the same type of geotextile being used, overlapping the existing geotextile. Geotextile panelsjoined by overlap will have the patch extend a minimum of 2 feet from the edge of any damaged area. The geotextile will not be placed until it can be anchored and protected with the specified covering within 48 homy or protected from exposure to ultraviolet light. In no case will material be dropped on uncovered geotextile from a height greater than 3 feet. 02270 -3 SECTION 02520 PORTLAND CEMENT CONCRETE PAVING PART 1- GENERAL 1.01 SUMMARY: A.

" 3.11 DISINFECTION FOR POTABLE WATER SYSTEMS: A. General G-) I. 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. Water main 16 -inch and larger in diameter must be swabbed with a soft pig prior to flushing if flow in the system is not adequate to maintain scouring velocity (2 fps) during flushing. The minimum uniform concentration of available chlorine used for disinfection shall be 50 mg/L, Use either the granulated /tablet or continuous feed method with modifications as described in 3.11 C or D below. 4. The chlorinated water shall be retained in the main at least 24 hours, during which 02660 -12 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 mgfL chlorine throughout the length of main. 5. 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 mg/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 T/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). 6. Collect a bacterial sample from the end of each line or 800 -1,000 feet and 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 coliferm organisms, the hydrostatic test may proceed. C. Tablet Method of Chlorine Application Use ANSI /AW WA 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 L Prior to applying chlorine, do a preliminary flush at a minimum velocity 692.5 feet per second in the main through an opening not less than not less thgn'/ oFthe main diameter. For 6 -inch through 12 -inch water mains, a single 2' /z- ineli' fire iiydran4 I opening is adequate.'. 2. Add the water and chlorine solution with the required concentration to fill -the m2iri` j completely. ) 3.12 TESTING: M w 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 main which is to be filled. Open a filling valve (the smallest one available) slightly. Allow the water main to 611 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. 02660 -13 3. 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 fresh 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. Then, 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. 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 two hour(—NLith 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, unc9ver, and ,hepair9r replace defective pipe, fitting or joints. Conduct additional tests and, repairs moil water main passes the test. C. Valve Operations: I. 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. 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 fully. 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. 02660 -14 E. 3. After hydrant has been flashed, 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 for leaks. Flow Test: 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 shall be conducted on the hydrant at the extreme locations for distance or highest elevation to determine the fire flow capability of the system. Static and flowing pressures and flow rates shall be recorded, and a copy forwarded to the Water Division. 02660 -15 N -) APPENDIX A Accepted Products for Water Distribution Materials WATER PIPE: (Ductile) ANSI /AWWA — A21.51/C151 American, Clow, Griffin, McWane, Tyler, and US Pipe Class 52 for direct buy piping unless other wise indicated or specified.
