Additional vibration isolation system requirements are provided in individual mechanical equipment specification sections. 1.02 QUALITY ASSURANCE A. TESTING: Unless the equipment incorporates unit construction using an integral rigid fiame or is specified otherwise, each item of mechanical equipment, along with its drive unit, shall be mounted on a rigid steel or steel and concrete base. Cast iron bases will be permitted only when the equipment is not furnished with a vibration isolation system. Where specified or noted on the drawings, the equipment, including the base, shall be mounted on or suspended fiom vibration isolators to prevent the transmission of vibration and mechanically transmitted sound to the supporting structure. Vibration isolation available internally in the equipment will not be considered equivalent and shall not be provided when vibration isolation as specified herein is required. Normally provided internal vibration isolators shall be replaced with rigid supports in such cases. Vibration isolators shall be selected in accordance with unit weight distribution to produce reasonably uniform deflections at each support. Bases, isolators and deflections shall be as specified in the Equipment Vibration Isolation Selection Guide. B. SEISMIC RESTRAlNTS: Where seismic restraint is required by the detailed specification, equipment and appurtenances resiliently mounted on spring or pad type vibration isolators, except for curb mounted equipment, shall be provided with seismic restraints or snubbers as specified herein. Seismic restraints for equipment mounted on vibration isolation curbs shall consist of slack stainless steel cables designed to provide 4 g restraint in the four primary horizontal directions. For all spring mounted equipment with an operating weight (dead plus live loads, including any integral supports) of 250 pounds or more, the selection of the particular seismic snubber shall be based upon complete dynamic analysis calculations using seismic response data derived for the system. Seismic response data are available in the soils report. Mahr Reservoir Remedial Improvement Vibration Isolation Systems 11021-1 The dynamic analysis report shall include a listing and explanation of all assumptions made which affect the calculations and the following information along the three principal orthogonal axes: 1. 2. 3. 4. The six natural frequencies of the system both with and without snubbing. The most probable movements (RMS values) at all mounting or combination mounting and snubber locations as well as at duct, pipe, and electrical connection points and the equipment extremities. Maximum accelerations at the center of each significant system element such as the motor, fan, compressor, heat exchanger, or engine as well as at the mounting or combination mounting and snubber locations, all expressed in g units. The most probable force (RMS value) at each mounting or mounting and snubber location expressed in pounds. It is the intent of this specification that the acceleration shall not exceed 4 g nor shall the excursion fiom center exceed 5/8 inch at the snubbers based on the RMS values. The capacity of each seismic snubber at 3/8-inch deflection shall be 3 to 4 times the load assigned to the mount grouping in its immediate area. When the analysis shows that levels higher than 4 g occur at the snubbers because of the maximum allowable amplitude, the Contractor shall suggest an alternate mount system based upon an additional dynamic analysis that will maintain the 4 g level. The Engineer will express a preference for either the higher g level or the alternate method at his option. The analysis shall have the equipment modeled as a single 3-dimensional rigid body composed of several rigidly attached lumped masses. The system must be conservative and have six natural modes and frequencies. The final solution shall be obtained as a combination of model responses in the form of a most probable value equal to the RMS values of the six modes. The report must be signed by a professional engineer registered in the State of California with demonstrated' competence in the field. C. DESIGN REQUIREMENTS: The Contractor shall cause all vibration isolation systems, including the isolators, seismic restraints and flexible connectors between the isolated equipment and associated piping, ducting andor electrical work, to be designed by an engineer Mahr Reservoir Remedial Improvement Vibration Isolation Systems 11021-2 1.03 qualified in this type of work.

CHLORINELFLUOROMETER MONITORING AND CONTROL Part 1 General 1.1 Work of this Section This Section presents the functional description for the operation and control of the algae monitoring and control system (chlorination system) and the reservoir de-stratification system (aeration system). This description aims to provide the CONTRACTOR with a complete understanding as to how the proposed systems will operate, and a guide for the provision of all instrumentation, controls, and programming required for the implementation of these systems. 1.2 RRlated Sections A. The Work of the following sections applies to the Work of this Section. Other sections of the specifications, not referenced below, shall also apply to the extent required for proper performance of the Work. 1.3 Chlorination System A. Overview- A chlorine feed system is provided to aid in the control of algae in the reservoir. The system is comprised of the following items: a. A recirculation system, which provides reservoir water for sampling and chemical mixing b. Water quality analyzers to monitor and provide input to the algae control system on reservoir water quality, c. A sodium hypochlorite injection system, which provide the algaecide agent. An aeration system, which main purpose is to ensure reservoir de-stratification (described in 1.61, provides for the mixing of the chemical stream into the reservoir. B. Control System Operation 1. Recirculation system- Water is drawn from the reservoir by a two- submersible-pump system mounted in a floating pontoon anchored near the middle of the reservoir. The recycled stream is pumped into a pipeline that enters the Control Building and returns back to the reservoir where it loops around the reservoir bottom. A series of nozzles mounted along the pipe loop ensures an even distribution of the recycled stream into the reservoir. Mahr Reservoir Remedial Improvements Instrumentation and Control Systems 16700-42 2. 3. Recirculation Pumps 1. .. 11. ... 111. Pump Selection- The local control panel shall have a two- position manual selector to select the active (duty) pump and inactive (stand-by) pump. Pump selection shall be reported to the Programmable Logic Controller (PLC) and Remote Terminal Unit (RTU). Pump Controls- The recirculation pumps shall have Hand/Off/Auto (HOA) switches. The running status of the pump and the position of HOA switches shall be reported to the PCP and RTU. The “Hand” mode of operation shall bypass the RTU and shall allow continued system operation in the event of main control system failure or maintenance. The “Hand” mode shall also bypass most pump protection features. Pump Failure- In the event that high-temperature is detected by the sensor devices built-in the pump motors a “Pump Failure’’ alarm shall be displayed in the local control panel, the PCP and RTU. In the auto mode this event shall stop the operating (duty) pump and call on operation the inactive (stand-by) pump. The pump with a “Pump Failure” condition will not run in Auto mode until the “Pump Failure” condition is cleared, which shall only be achieved by manually acknowledging the alarm and turning the HOA switch to “Off and back to “Auto”. A “Pump failure” condition shall not stop a pump operated in manual (“Hand”). Water Quality Analyzers - An in line fluorometer and an in-line chlorine residual analyzer shall be tapped in the recirculation line inside the Control Building for water sampling and testing. i. .. 11. Chlorine analyzer - A constant flow shall be diverted to the analyzer as required by the instrument manufacturer to prevent fouling of the cell electrodes. Analysis data shall be reported in regular intervals (initially set to 15 minutes) to the PCP and RTU for monitoring and logging. Common alarm signal generated by the instrument shall be reported to the control panel and PCP and RTU. Sampling flow shall be drained to a 20-gallons drum fitted with a high level switch. High water alarm shall be annunciated at the control panel and PCP and RTU. The setting of the high water level shall be set as to provide the continuous operation of the analyzer for over 48 hours without spilling. Fluorometer- A sample line shall tee off the recirculation line, run through the fluorometer and return to the recirculation line. Ball valves and check valves shall be installed as necessary in both the sample and recirculation line that bypasses the fluorometer, to ensure that the analyzer is fed with sufficient and continuous flow as required by the instrument Mahr Reservoir Remedial Improvements Instrumentation and Control Systems 1670043 manufacturer. Analysis data shall be reported in regular intervals (initially set to 15 minutes) to the PCP and RTU for monitoring and logging. Common alarm signal generated by the instrument shall be reported to the PCP and RTU i. An electronic metering pump draws sodium hypochlorite from two tanks and injects the solution in the recirculation line. The system is provided with a back pressure sustaining valve on the pump outlet to prevent flow by gravity through the vessels when the pump is off. The pump has an HOA switch, and the status of the HOA switch and the running status of the pump shall be displayed by the SCADA control system. In all modes of operation, the proportion of disinfectant drawn from each tank shall be adjusted manually by throttling (or closing) the isolation valve of each vessel. In the Auto mode of operation, the odoff status of the pump shall be governed by the control system. ii. The control system shall operate to maintain the chlorine residual in the reservoir within two distinct ranges depending on the fluorometer readings. If the fluorometer reading is below the selected threshold, indicating low algae biomass, the chlorine residual shall be kept within the lower range, starting to inject chlorine when the chlorine residual falls below the range and stopping if it rises above. Similarly, if high algae biomass is detected, the reservoir chlorine residual shall be kept in the higher range, injecting chlorine as the chlorine residual falls below the upper range and stopping when it reaches its upper limit. All these set-points shall be available for modification by the operator. Initial set-points shall be as follows: 4. Sodium hypochlorite system- Algae biomass threshold = 100pgLchlorophyll A Lower Chlorine Residual range: Lower bound= 1 mg/L; Upper bound = 2 m& Upper Chlorine Residual range: Lower bound= 2 mgL; Upper bound = 3 mg/L With the initial values the control system shall operate as follows: - ~~ ~~ Chemical Pump Status ON OFF If Chlorophyll A <lOOpg If Chlorophyll A >=lOOpg And Clz <=1 mg/l And Clz <=2 mg/l And Clz >=2 mg/l And Clz >=3 mg/l iii. Interlocks -Chemical pump operation shall be interlocked with the aeration system such that the aeration system shall be ON Mahr Reservoir Remedial Improvements Instrumentation and Control Systems 16700-44 or turn ON at the start of the chemical feed pump. If a fluorometer or chlorine analyzer failure is reported the system shall shut off. iv. The control system shall also accept and display a maximum run time duration, varying between 0.0 and 48.0 hours. The actual run time for each active duration shall also be displayed. In the Auto mode, when the actual run time reaches the maximum run time duration, an "Excessive Run Duration" alarm will be displayed by the control system, preventing further automatic operation of the metering pump until manually reset as a fimction within the control system. 1.4 Aeration System Overview- An aeration system is provided to prevent the formation of reservoir stratification and to assist with the mixing of the chlorine in the reservoir. A duplex reciprocating blower will feed air into a perforated pipe header that loops around the bottom of the lake. The blower has an HOA switch, and the status of the HOA switch and the running status of the blower shall be reported to and displayed by the PCP and RTU.

In the event potential Historical, Archeological, or Cultural Resources (herein after cultural resources) are discovered during subsurface excavations at the site of construction, the following procedures shall be instituted: 1) The Engineer shall issue a “Stop Work Order” directing the Contractor to cease all construction operations at the location of such potential cultural resources find. If the find includes human remains, the County Coroner must be contacted immediately. 2) Such “Stop Work Order” shall be effective until such time as a qualified archeologist can be called to evaluate the importance of these potential cultural resources and make recommendations to the State Water Resources Control Board Cultural Resources Officer (CRO). Any “Stop Work Order” shall contain the following: a) A clear description of the work to be suspended; b) Any instructions regarding issuance of hrther orders by the Contractor for material services; c) Guidance as the action to be taken on subcontracts; d) Any suggestions to the Contractor as to minimization of his costs; e) Estimated duration of the temporary suspension. If the archeologist in consultation with the SWRCB CRO determines that the potential find is an important resource and warrants further investigation and/or mitigation, the Engineer shall extend the duration of the “Stop Work Order” in writing, and the Contractor shall suspend work at the location of the find. Equitable adjustment of the construction contract shall be made in the following manner: 1) Time Extension If the work temporarily suspended is on the “critical path”, the total number of days for which the suspension is in effect shall be added to the number of allowable contract days. IC , BP-18 Issue Date: November 7,2003 State Revolving Fund Loan Program CCR and Boilerplate If a portion of work at the time of such suspension is not on the “critical path”, but subsequently becomes work on the critical path, the allowable contract time will be computed fkom the date such work is classified as on the critical path. - 2) Additional Comuensation If, as a result of a suspension of the work, the Contractor sustains a loss which could not have been avoided by his judicious handling of forces, and equipment, or redirection of forces or equipment to perform other work on the contract, there shall be paid to the Contractor an amount as determined by the Engineer to be fair and reasonable compensation for the Contractor’s actual loss in accordance with the following: a) Idle Time of Equipment Compensation for equipment idle time will be determined on a force account (time and materials) basis, and shall include the cost of extra moving of equipment and rental loss. The right-of-way delay factor for each classification of equipment shown in the California Department of Transportation publication entitled, Eauiument Rental Rates and the General Prevailing Wage Rates, will be applied to any equipment rental rates. b) Idle Time of Labor Compensation for idle time of workers will be determined by the Engineer as “Labor” less any actual productivity factor of this portion’ of the work force. c) Increased Costs of Labor and Materials Increased costs of labor and materials will be compensated only to the extent such increase was in fact caused by the suspension, as determined by the Engineer. Compensation for actual loss due to idle time of either equipment or labor shall not include markup for profit. The hours for which compensation will be paid will be the actual normal working time during which such delay condition exists, but will in no case exceed eight hours in any one day. The days for which compensation will be paid shall be full or partial calendar days, excluding Saturdays, Sundays, and legal holidays, during the existence of such delay. - Issue Date: November 7,2003 BP-19 State Revolving Fund Loan Program CCR and Boilelplate /I 10 - COMPLIANCE GUIDELINES FOR SRF LOAN PROGRAM MBE/WBE CONTRACT PROVISIONS OF THE STATE WATER RESOURCES CONTROL BOARD (SWRCB) DIVISION OF FINANCIAL, ASSISTANCE RELATIVE TO THE UTILIZATION OF MINORITY BUSINESS ENTERPRISE (MBE) AND WOMEN BUSINESS ENTERPRISE (WBE) ON CLEAN WATER PROGRAM CONSTRUCTION CONTRACTS IN CALIFORNIA This document and attachments shall be included by the owner as a contract provision for all construction contracts exceeding $10,000.

Provide quarterly reports on MBE/WBE procurements to DFA. - Section 3: “Good Faith” Effort Process Any public or private entity receiving federal funds must demonstrate that efforts were made to attract MBEMEs on any SRF contracts. The process to attract MBEWEs is referred to as the “good faith” effort. This effort requires the recipient, prime contractor and any subcontractors to take the steps listed below to assure that MBE/WBEs are used whenever possible as sources of supplies, construction, equipment or services. Failure to take the steps outlined below and submit Form 4, Prime Contractor/Recipient Selected MBEmEs, prior to bid opening, shall cause the bid to be rejected as non-responsive. Use Forms 1 through 6 to document the process. If it is not practical or possible to comply with one or more of the five steps, prepare an explanation and submit it with the ATA package. STEP 1: Divide the total requirements, when economically feasible, into small tasks or quantities to permit maximum participation. Evidence submitted must illustrate that the work was divided into small proprietary portions (e.g. paving, electrical, landscaping, revegetation). STEP 2: Establish deliverv schedules, when work requirements permit, that encourape maximum MBE/WBE participation. STEP 3: Use the services of the U.S. Small Business Administration (SBA) and the Minority Business Development Agency (MBDA) of the U. S. Department of Commerce JDOC) in soliciting qualified MBE/WBEs. Utilization of these resources is required at no cost. These agencies offer several services, including Internet access to databases of MBE/WBEs. For additional assistance, the recipient or contractor could telephone the local offices 9f both agencies in their area (SBA Minority Enterprise Development Offices and DOC MBDA Regional Centers). The Internet web sites also include names, addresses, and phone or fax numbers of local SBA and MBDA centers. There are contact phone numbers listed in Step 5 that will assist you in reaching the two offices if the Internet is unavailable. Do not write to these sources. The prime contractor must provide documentation that the local SBNMBDA offices or web sites were notified of the contracting opportunity (allow at least five working days for a response). Documentation must not only include the efforts to contact the information sources and list the contract opportunity, but also the solicitation and response to the bid request. STEP 4: Include qualified MBE/WBEs on solicitation lists and record the information. Solicitation should be as broad as possible. The following web sites include a list of available sources for expanding the search for eligible MBENBEs: http://www.sba.aov and http://www.mbda.gov. If MBENBE sources are not located, explain why and describe the efforts made. See Step 5 for more detailed information. rc For all contracts, the prime contractor must send invitations to at least three (or all, if less than three) MBENBE vendors for each item of work referred by sources contacted. The invitations must adequately specify the items for which bids are requested. The record of “good faith” efforts must indicate a real desire for a positive response, such as a certified mail receipt or a documented telephone conversation. (A regular letter or an BP-22 Issue Date: November 7,2003 State Revolving Fund Loan Program CCR and Boilelplate unanswered telephone call is not an adequate “good faith” effort). A list of all sub- bidders, including the bidders not selected, and bid amount for each item of work must be submitted. A sample list is shown in Form 5, Sample Summary of Bids Received from Subcontractors. If a low bid was not accepted, an explanation must be provided. Name and Address U.S. Small Business Administration 455 Market Street, Suite 600 San Francisco, CA 94105 STEP 5: Solicit available MBEs and WBEs whenever thev are potential sources. The prime contractor must provide invitations to MBE/WBE sub-bidders at least seven working days prior to the bid opening date.

The Offerer's or Bidder's attention is called to the "Equal Opportunity Clause" and the "Standard Federal Equal Employment Specifications" set forth herein. 2. The goals and timetables for minority and female participation, expressed in percentage terms for the contractor's aggregate workforce in each trade on all construction work in the covered area, are as follows: Time- Goals for minority participation Goals for female participation tables for each trade for each trade Contract Dates: 16.9% 6.9% Contact the Division of Financial Assistance, Ken Gonzales at (916) 341-5683 for assistance with the minority goal and tables (gonzalesk@swrcb.ca.gov). The Office of Federal Contract Compliance Programs' web site for compliance issues and preaward registry is at http://www.dol.gov/esa/welcome. These goals are applicable to all the Contractor's construction work (whether or not it is Federal or federally assisted) performed in the covered area. If the contractor performs construction work in a geographical area located outside of the covered area, it shall apply the goals established for such geographical area where the work is actually performed. With regard to this second area, the contractor also is subject to the goals for both its federally involved and non-federally involved construction. The Contractor's compliance with the Executive Order and the regulations in 41 CFR Part 60-4 shall be based on its implementation of the Equal Opportunity Clause, specific affirmative action obligations required by the specifications set forth in 41 CFR 60-4.3(a), and its efforts to meet the goals. The hours of minority and female employment and training must be substantially uniform throughout the length of the contract, and in each trade, and the contractor shall make a good faith effort to employ minorities and women evenly on each of its projects. The transfer of minority or female employees or trainees from Contractor to Contractor or from project to project for the sole purpose of meeting the Contractor's goals shall be a violation of the contract, the Executive Order and the regulations in 41 CFR Part 60-4. Compliance with the goals will be measured against the total work hours performed. 3. The Contractor shall provide written notification to the Director of the Office of Federal Contract Compliance Programs (notify the applicable Regional Office found at www.dol.gov/esa) within 10 working days of award of any construction subcontract in excess of $10,000 at any tier for construction work under the contract resulting from this solicitation. The notification shall list the name, address and telephone number of the subcontractor; employer identification number of the subcontractor; estimated dollar amount of the subcontract; estimated starting and completion dates of the subcontract; and the geographical area in which the subcontract is to be performed. 4. As used in this Notice, and in the contract resulting from this solicitation, the "covered area" is (insert description of the geographical areas where the contract is to be performed giving the state, county and city, if any). § 60-4.3 Equal opportunity clauses (in relevant part) Standard Federal Equal Employment Opportunity Construction Contract Specifications (Executive Order 11246) Issue Date: November 7, 2003 BP- 39 State Revolving Fund Loan Program CCR and Boilerplate 1. As used in these specifications: a. "Covered area" means the geographical area described in the solicitation from which this contract resulted; b. "Director" means Director, Office of Federal Contract Compliance Programs, United States Department of Labor, or any person to whom the Director delegates authority; c. "Employer identification number" means the Federal Social Security number used on the Employer's Quarterly Federal Tax Return, U.S. Treasury Department Form 941. d. "Minority" includes: (i) Black (all persons having origins in any of the Black African racial groups not of Hispanic origin); (ii) Hispanic (all persons of Mexican, Puerto Rican, Cuban, Central or South American or other Spanish Culture or origin, regardless of race); (iii) Asian and Pacific Islander (all persons having origins in any of the original peoples of the Far East, Southeast Asia, the Indian Subcontinent, or the Pacific Islands); and (iv) American Indian or Alaskan Native (all persons having origins in any of the original peoples of North America and maintaining identifiable tribal affiliations through membership and participation or community identification). 2. Whenever the Contractor, or any Subcontractor at any tier, subcontracts a portion of the work involving any construction trade, it shall physically include in each subcontract in excess of $10,000 the provisions of these specifications and the Notice which contains the applicable goals for minority and female participation and which is set forth in the solicitations from which this contract resulted. 3. If the Contractor is participating (pursuant to 41 CFR 60-4.5) in a Hometown Plan approved by the U.S. Department of Labor in the covered area either individually or through an association, its affirmative action obligations on all work in the Plan area (including goals and timetables) shall be in accordance with that Plan for those trades which have unions participating in the Plan. Contractors must be able to demonstrate their participation in and compliance with the provisions of any such Hometown Plan. Each Contractor or Subcontractor participating in an approved Plan is individually required to comply with its obligations under the EEO clause, and to make a good faith effort to achieve each goal under the Plan in each trade in which it has employees. The overall good faith performance by other Contractors or Subcontractors toward a goal in an approved Plan does not excuse any covered Contractor's or Subcontractor's failure to take good faith efforts to achieve the Plan goals and timetables. 4. The Contractor shall implement the specific affirmative action standards provided in paragraphs 7 a through p of these specifications. The goals set forth in the solicitation from which this contract resulted are expressed as percentages of the total hours of employment and training of minority and female utilization the Contractor should reasonably be able to achieve in each construction trade in which it has employees in the covered area. Covered Construction contractors performing construction work in geographical areas where they do not have a Federal or federally assisted construction contract shall apply the minority and female goals established for the geographical area where the work is being performed. Goals are published periodically in the Federal Register in notice form, and such notices may be obtained from any Office of Federal Contract Compliance Programs office or from Federal procurement contracting officers. The Contractor is expected to make substantially uniform progress in meeting its goals in each craft during the period specified. 5. Neither the provisions of any collective bargaining agreement, nor the failure by a union with whom the Contractor has a collective bargaining agreement, to refer either minorities or women shall excuse the Contractor's obligations under these specifications, Executive Order 11246, or the regulations promulgated pursuant thereto. 6. In order for the non-working training hours of apprentices and trainees to be counted in meeting the goals, such apprentices and trainees must be employed by the Contractor during the training period, and the Contractor must have made a commitment to employ the apprentices and trainees at the completion of their training, subject to the availability of employment opportunities. Trainees must be trained pursuant to training programs approved by the U.S. Department of Labor. Issue Date: November 7, 2003 BP- 40 State Revolving Fund Loan Program CCR and Boilerplate 1. The Contractor shall take specific affirmative actions to ensure equal employment opportunity. The evaluation of the Contractor's compliance with these specifications shall be based upon its effort to achieve maximum results from its actions. The Contractor shall document these efforts fully, and shall implement affirmative action steps at least as extensive as the following: a. Ensure and maintain a working environment free of harassment, intimidation, and coercion at all sites, and in all facilities at which the Contractor's employees are assigned to work. The Contractor, where possible, will assign two or more women to each construction project. The Contractor shall specifically ensure that all foremen, superintendents, and other on-site supervisory personnel are aware of and carry out the Contractor's obligation to maintain such a working environment, with specific attention to minority or female individuals working at such sites or in such facilities. b. Establish and maintain a current list of minority and female recruitment sources, provide written notification to minority and female recruitment sources and to community organizations when the Contractor or its unions have employment opportunities available, and maintain a record of the organizations' responses. c. Maintain a current file of the names, addresses and telephone numbers of each minority and female off-the-street applicant and minority or female referral from a union, a recruitment source or community organization and of what action was taken with respect to each such individual. If such individual was sent to the union hiring hall for referral and was not referred back to the Contractor by the union or, if referred, not employed by the Contractor, this shall be documented in the file with the reason therefore, along with whatever additional actions the Contractor may have taken. d. Provide immediate written notification to the Director when the union or unions with which the Contractor has a collective bargaining agreement has not referred to the Contractor a minority person or woman sent by the Contractor, or when the Contractor has other information that the union referral process has impeded the Contractor's efforts to meet its obligations. e. Develop on-the-job training opportunities and/or participate in training programs for the area which expressly include minorities and women, including upgrading programs and apprenticeship and trainee programs relevant to the Contractor's employment needs, especially those programs funded or approved by the Department of Labor. The Contractor shall provide notice of these programs to the sources compiled under 7b above. f. Disseminate the Contractor's EEO policy by providing notice of the policy to unions and training programs and requesting their cooperation in assisting the Contractor in meeting its EEO obligations; by including it in any policy manual and collective bargaining agreement; by publicizing it in the company newspaper, annual report, etc.; by specific review of the policy with all management personnel and with all minority and female employees at least once a year; and by posting the company EEO policy on bulletin boards accessible to all employees at each location where construction work is performed. g. Review, at least annually, the company's EEO policy and affirmative action obligations under these specifications with all employees having any responsibility for hiring, assignment, layoff, termination or other employment decisions including specific review of these items with onsite supervisory personnel such as Superintendents, General Foremen, etc., prior to the initiation of construction work at any job site. A written record shall be made and maintained identifying the time and place of these meetings, persons attending, subject matter discussed, and disposition of the subject matter. h. Disseminate the Contractor's EEO policy externally by including it in any advertising in the news media, specifically including minority and female news media, and providing written notification to and discussing the Contractor's EEO policy with other Contractors and Subcontractors with whom the Contractor does or anticipates doing business. i. Direct its recruitment efforts, both oral and written, to minority, female and community organizations, to schools with minority and female students and to minority and female recruitment and training organizations serving the Contractor's recruitment area and employment needs. Not later than one month prior to the date for the acceptance of applications for apprenticeship or other training by any recruitment source, the Contractor shall send written notification to organizations such as the above, describing the openings, screening procedures, and tests to be used in the selection process. Issue Date: November 7, 2003 BP- 41 State Revolving Fund Loan Program CCR and Boilerplate j. Encourage present minority and female employees to recruit other minority persons and women and, where reasonable, provide after school, summer and vacation employment to minority and female youth both on the site and in other areas of a Contractor's work force. k. Validate all tests and other selection requirements where there is an obligation to do so under 41 CFR Part 60-3. 1. Conduct, at least annually, an inventory and evaluation at least of all minority and female personnel for promotional opportunities and encourage these employees to seek or to prepare for, through appropriate training, etc., such opportunities. m. Ensure that seniority practices, job classifications, work assignments and other personnel practices, do not have a discriminatory effect by continually monitoring all personnel and employment related activities to ensure that the EEO policy and the Contractor's obligations under these specifications are being carried out. n. Ensure that all facilities and company activities are Non-Segregated except that separate or single-user toilet and necessary changing facilities shall be provided to assure privacy between the sexes. o. Document and maintain a record of all solicitations of offers for subcontracts from minority and female construction contractors and suppliers, including circulation of solicitations to minority and female contractor associations and other business associations. p. Conduct a review, at least annually, of all supervisors' adherence to and performance under the Contractor's EEO policies and affirmative action obligations. 8. Contractors are encouraged to participate in voluntary associations which assist in fulfilling one or more of their affirmative action obligations (7a through p). The efforts of a contractor association, joint contractor-union, contractor-community, or other similar group of which the contractor is a member and participant, may be asserted as fulfilling any one or more of its obligations under 7a through p of these Specifications provided that the contractor actively participates in the group, makes every effort to assure that the group has a positive impact on the employment of minorities and women in the industry, ensures that the concrete benefits of the program are reflected in the Contractor's minority and female workforce participation, makes a good faith effort to meet its individual goals and timetables, and can provide access to documentation which demonstrates the effectiveness of actions taken on behalf of the Contractor. The obligation to comply, however, is the Contractor's and failure of such a group to fulfill an obligation shall not be a defense for the Contractor's noncompliance. 9. A single goal for minorities and a separate single goal for women have been established. The Contractor, however, is required to provide equal employment opportunity and to take affirmative action for all minority groups, both male and female, and all women, both minority and non-minority. Consequently, the Contractor may be in violation of the Executive Order if a particular group is employed in a substantially disparate manner (for example, even though the Contractor has achieved its goals for women generally, the Contractor may be in violation of the Executive Order if a specific minority group of women is underutilized). 10. The Contractor shall not use the goals and timetables or affirmative action standards to discriminate against any person because of race, color, religion, sex, or national origin. 11. The Contractor shall not enter into any Subcontract with any person or firm debarred from Government contracts pursuant to Executive Order 11246. 12. The Contractor shall carry out such sanctions and penalties for violation of these specifications and of the Equal Opportunity Clause, including suspension, termination and cancellation of existing subcontracts as may be imposed or ordered pursuant to Executive Order 11246, as amended, and its implementing regulations, by the Office of Federal Contract Compliance Programs. Any Contractor who fails to carry out such sanctions and penalties shall be in violation of these specifications and Executive Order 11246, as amended. 13. The Contractor, in fulfilling its obligations under these specifications, shall implement specific affirmative action steps, at least as extensive as those standards prescribed in paragraph 7 of these specifications, so as to achieve maximum results from its efforts to ensure equal employment opportunity. If the Contractor fails to comply with the requirements of the Executive Order, the implementing regulations, or these specifications, the Director shall proceed in accordance with 41 CFR 60-4.8. Issue Date: November 7, 2003 BP- 42 State Revolving Fund Loan Program CCR and Boilerplate 14. The Contractor shall designate a responsible official to monitor all employment related activity to ensure that the company EEO policy is being carried out, to submit reports relating to the provisions hereof as may be required by the Government and to keep records. Records shall at least include for each employee the name, address, telephone numbers, construction trade, union affiliation if any, employee identification number when assigned, social security number, race, sex, status (e.g., mechanic, apprentice trainee, helper, or laborer), dates of changes in status, hours worked per week in the indicated trade, rate of pay, and locations at which the work was performed. Records shall be maintained in an easily understandable and retrievable form; however, to the degree that existing records satisfy this requirement, contractors shall not be required to maintain separate records. 15. Nothing herein provided shall be construed as a limitation upon the application of other laws which establish different standards of compliance or upon the application of requirements for the hiring of local or other area residents (e.g., those under the Public Works Employment Act of 1977 and the Community Development Block Grant Program). 15 - ELIMINATION OF SEGREGATED FACILITIES NOTICE TO PROSPECTIVE FEDERALLY-ASSISTED CONSTRUCTION CONTRACTORS (a) A Certification of Non-Segregated Facilities, as required by the May 9, 1967 Order (32 F.R. 7439, May 19, 1967) on Elimination of Segregated Facilities, by the Secretary of Labor, must be submitted prior to the award of a Federally-assisted construction contract exceeding $10,000 which is not exempt from the provisions of the Equal Opportunity Clause.
