ENVIRONMENTAL PROTECTION AGENCY REGION II GUIDANCE AND PROCEDURES FOR COMPLIANCE WITH MINORITY BUSINESS ENTERPRISE REQUIREMENTS PART I Introduction The purpose of this guidance is to outline procedures for use by the grantees, A/E consultants and construction contractors in complying with the Environmental Protection Agency, Region II, Minority Business Enterprise {MBE) Program for the Implementation of the EPA policy pub- lished in the Federal Register on December 26, 1978 {copy attached). The purpose of this Program is to raise the level of MBE participation in EPA funded projects to a level con~nensurate with their capabilities and availability. These procedures are designed to implement EPA Policy which requires affirmative steps, including goals to be achieved through a result-oriented program. The EPA regulations 40 CFR 35.936-7, 40 CFR 35.937-12{b), 40 CFR 35.938- 9{b){2), Appendix C-l{14}, and Appendix C-2{9} require grantees and construction contractors to take affirmative steps to utilize minority- owned businesses in the procurement of engineering and construction services and supplies. The EPA, and in particular, its Regional Administrators, have the duty under 40 CFR, Parts 30 and 35 to insure compliance with all grant regulations, requirements and conditions. The Director of the Office of Civil Rights and Urban Policy has the responsibility for establishing an MBE program in coordination with the Director of the Water Division. The Director of the Office of Civil Rights and Urban Policy will determine compliance with Minority Business Enterprise requirements. The grantee in its role as a public trustee assumes primary responsi- bility to achieve an acceptable level of MBE use. This primary responsi- bility is a basic condition of its grant award. All applicants/grantees are required to take positive efforts to use MBE. As an aid to the grantee, A/E consultants and construction contractors, the U. S. Department of Commerce has locally funded offices of the Office of Minority Business Enterprise, which will provide MBE resource lists, technical assistance and on-going information. Additional MBER - 1 of 26 -2- information may be obtained from the Office of Civil Rights and Urban Policy and the Water Division, Region II. The Civil Rights Director and his/her MBE coordinators are also available for consultation and advice regarding the utilization of minority business enterprises. Applicability All grantees receiving financial grant assistance on EPA funded projects involving architectural and engineering consulting services and con- struction contractors are subject to the policy and procedures described herein. Definitions Minority Business Enterprise. A business at least 51 percent of which is owned and controlled by minority group members, or in the case of a publicly-owned business, at least 51 percent of the stock of which is owned and controlled by minority group members. The minority owner- ship must exercise actual day-to-day management. Minority Group Members· Black Americans, Hispanic Americans, Asian Americans, American Indians, American Eskimos, and American Aleuts. EPA Region II will conduct reviews in cooperation with other Federal, State, local, and private agencies to verify that an MBE contractor or supplier performs a conmercially useful function and is not dominated by nonmtnority sources of supply. Discovery of the use of a "sham" MBE firm or a legitimate MBE firm being used to subvert the purposes of the program will require correctly, or enforcement action. PART II Policy Statement The applicant/grantee's policy-making body (Authority, Board, Council, etc.) or Chief Executive Officer (e.g., Mayor) is required to issue a policy statement which expresses commitment to the MBE program and which utilizes the Regional goals or such goals as may be established by the grantee to express the percentage MBE participation which the applicant shall strive to achieve. The statement must outline the levels of MBER - 2 of 26 -3- responsibility, beginning with the Chief Executive Officer who will be responsible and accountable for carrying out the program. The policy statement shall be circulated to the applicant's managers, supervisors, and employees, as well as to minority economic development agencies Xnd organizations, contractors' associations (both minority and non-minority), and newspapers, magazines, and other appropriate media {both minority and non-minority). The policy statement should be conspicuously posted in all offices where minority entrepreneurs and employees may have occasion to visit. A copy of the policy statement and a list of the organizations, asso- ciations and communications media to which it is to be distributed, shall be supplied to the Director, Office of Civil Rights and Urban Policy, USEPA, Region II, at the time of grant application. B. Identification of an MBE Person An "MBE Officer" shall be designated by the grantee's Chief Executive Officer. In order to achieve maximum program efficiency, it is essen- tial that the individual(s) selected must be: 1. Familiar with and capable of communicating and interpreting the applicant's procurement procedures and requirements, as well as EPA contracting and subcontracting procedures and requirements. 2. Understanding of small and minority business problems. 3. Capable of communicating effectively with minority businesses and management. 4. Able to maintain a good rapport with the minority community. 5. Familiar with local resources and services available to aid Minority Business Enterprises. The name, address, and telephone number of the designated MBE Officer shall be included with the application supplied to the Director, Office of Civil Rights and Urban Policy, USEPA, Region II, at the time of grant application submission. C. MBE Percentage Goals~ EPA Region II has determined that ~etween 10-25% of the dollar amount of all contracts awarded for A/E consultant services and the construction *so as not to distort the regional picture the above range of numbers as a goal has been computed not to include Puerto Rico which is being cal- culated as a separate case. ~4BER - 3 of 26 -4- and supply services required in the plans and specifications are to be committed to minority-owned businesses. The grantee in its role as a public trustee assumes primary responsibility to achieve an acceptable level of MBE participation. Each grantee may establish a numerical goal or goals under V, B, (2), (b) of the EPA policy statement.. The EPA Region II goal is based on the minority consistuency in the geographical areas'genuinely accepted as demarking the reasonable limits of local labor markets, such as the Standard Metropolitan Statistical Area (SMSA) as currently defined by the U.S. Office of Statistical Standards. Some EPA Regions have chosen to set as a goal a percentage of the total dollar value of all A/E contracts approved and to set as a separate qoal a percentage of the total dollar value of all construc- tion contracts and service approved. Region II's goal-oriented program involves establishing an MBE goal which represents a percent- age of the total dollar value of all contracts approved. Where the project is already underway, any Invitation for Bids (IFB) or Request for Proposals (RFP) issued by the grantee and procurement of subagreements on or after February l, 1979 are subject to this policy and the grantee must take steps to implement procedures necessary to establish a goal-oriented MBE program (including the issuance of addenda to current IFB's and RFP's). Achievement of specified MBE goals by A/E consultant, prime contractor or subcontractor goals or adequate documentation or justification of failure to meet goals must be required by grantee for submission to the Director of Civil Rights and Urban Policy for review and appropriate action. Adequate planning is critical to insure that MBEs have an equitable opportunity to participate in A/E consultaing, design and construction contracts and subcontracts. The applicant/grantee may establish its own goals for each of the 3 steps of the grant process based on the availability and capability of MBEs to do the work. Such goals are not expected to be lower than 10% minimum level. EPA Region II requires an Affirmative Action Plan type methodology to be followed in setting goals. The following outline is recommended: MBER 4 of 26 -5- 1. The goal must reflect a cognizance of the current percentage of minority population in the area. 2. The goal must be based on projections of contract and subcontract awards. 3. The goal must be related to the availability of MBEs. 4. The goal must reflect the full range of A/E consulting and con- structton activities anticipated by the plans and specifications and should, to some extent, be directed at expanding minority participation in those areas of A/£ consulting and, construction contracting and subcontracting where past participation has been minimal or non-existent. The setting of goals is a method of matching projected A/Econsulting, contracting and subcontracting opportunities with available MBEs. The geographic basis for assessing MBE availability will vary with the type of work to be performed or the type of supplies to be procured. In general, in defining the geographical boundaries for determining the availability of MBEs in specific A/E consulting, construction contract- ing or subcontracting areas, the grantee will follow a common sense approach and should apply the same criteria that the applicant generally has applied to non-minority firms. It should be kept in mind that if the data collected to develop grmntee goals particularly MBE availability, is inadequate or is assessed to be superficial, EPA Region II may find the goal unacceptable and impose an appropriate goal. An MBE program, including the percentage goal, and the steps the grantee will take to achieve the g0al must be submitted to the Director, Office of Civil Rights and Urban Policy, USEPA, Region II, at the time of application. Specific goals established after application but prior to the issuance of solicitation document shall also be promptly submitted. PART III Procedures by Applicant/Grantee to Ensure MBE Participation 1. Once the goal has been set, affirmative action techniques should be developed to meet the goal. The techniques must include but not be limited to: MBER - 5 of 26 -6- a. Designing the project and the bidding package to provide MBEs access to meaningful prime contracting and subcontracting opportunities by trade discipline and by separable units. b. Designing specific plans and specifications designed to increase potential ).~E participation. This can take the form of breaking down large contracts into smaller ones, and of designing facilities' taking into consideration the type of work for which minority firms are available and capable. c. Using the MBEs in construction management contracts. d. Encouraging the formation of joint ventures among MBEs and between minority and majority firms which provide opportunity for MBEs to gain experience. e. Providing plans and soecifications to the State and local minority busi- ness organizations anJ associations, including the State OMBE offices. These must be provided in a timely manner in order to allow MBEs adequate time to develop responsive and responsible bids for contracts or proposals for subcontracts. f. Establishing payment an~ delivery schedules so as to minimize cash flow problems faced by minority firms. g. Providing a source list of minority A/E consulting and construction con- tractors and suppliers to those firms who have received the bid or proposal package. h. Informing all prospective bidders and proposers in writing of the EPA policy concerning the utilization of minority firms when announcements for Invitation for Bids (IFB) or Requests for Proposals (RFP) are issued by the grantee. i. Including the appropriate MINORITY BUSINESS ENTERPRISE PARTICIPATION SPECIFICATIONS set out in Appendix I and Appendix II of this guidance in all RFPs and bid specifications or such other solicitation pro- visions as may be approved by EPA making certain that the appropriate percentage goal figure is included in all specifications and requests for bids or proposals. J. Keeping EPA, Region II, Office of Civil Rights and Urban Policy in- formed of all contract awards or changes in plans for awards of approved proposed contracts. MBER 6 of 26 -7- The applicant must take affirmative steps to insure equitable oppor- tunity for minority firms to participate in EPA assisted projects. The name and addresses of all minority consulting firms contacted and their response and the names of those intended to be utilized must be promptly submitted by the applicant to be forwarded to Region II's Office of Civil Rights and Urban Policy for review and approval prior to grant offer or prior to contract approval. The applicant should contact ten {10) or more minority firms to ascertain their interest, capability and availability to serve as prime consultants, joint venturers, or as subconsultants in the facilities planning, design service, contract management and environ- mental impact statement process under consideration. Documentation of the MBEs' response must be made available to the EPA, Region II Office of Civil Rights and Urban Policy upon request. Applicants/ grantees will contact out-of-state minority firms if none can be obtained in-state to meet requirements. Consulting and subcontracting possibilities include, but are not limited to the following: a. Step 1 (Facility Planning). (1) Engineering report. (2) Environmental assessment statement. {3) Infiltration/Inflow analysis. b. Step 2 (Design) {1) Design {a) Pump station force main. (b) Sewage treatment plant. (c) Interceptor. (d) Collection system. (2) 0 & M Manual development c. Step 3 (Construction) (1) Site preparation. (2) Foundation. MBER - 7 of 26 -8- (3) Shell. (4) Roof. (5) Walls. (6) Electrical. (7) Plumbing and mechanical. (8) Finish interior. (9) Exterior appurtenances. (10) Site completion/landscaping. (ll) Test/start-up operation. 4. In order for the applicant/grantee to assure its compliance with EPA regulations, the applicant should include, as part of its responsibility evaluation criteria, affirmative efforts taken for the utilization of minority firms for facilities planning, design and construction services to be required by the applicant/grantee. In addition, the applicant/ grantee must notify all prospective contractors and consultants by announcement that approval of contract award may be withheld unless it can be shown to the applicant/grantee that positive affirmative efforts as described herein have been or will be taken to utilize minority A/E firms either as joint venturers or subcontractors. 5. Because many minority firms are small operations, the capabili- ties of such firms are especially unique in facilities planning and design services, contract management services, and environmental impact statement services. Since there may be certain labor and over- head cost advantages realized by the applicant/grantee in utilizing a small firm in these situations, applicant/grantees are expected to aggressively pursue the utilization of such minority firms as prime consultants. 6. EPA will monitor projects on a "random sample" basis. Documentation of efforts made to utilize minority firms must be maintained'by all applicant/grantees and their contractors for review by the Office of Civil Rights and Urban Policy. MBER - 8 of 26 -9- 7. For reference, applicants/qrantees wil) be orovided with.a l!st by EPA, Region II of minority firms experienced in archttec:uram, engineering, construction and other professional services. The list is intended as a resource reference only, and not intended to re- strict or limit contact with other minority firms not listed. 8. The applicant/grantee's MBE proaram should assist MBEs in overcominq barriers to program participation. This assistance should be offered directly by the applicant, as well as by referral to other assistance agencies. 9. The applicant/grantee should work closely with financial institutions, insurance and bondin~ companies, and prime contractors in an effort to alleviate financial barriers to nrogram participation. PART IV MBE Set-Asides While not required by EPA policy, a pro~ram to implement MBE set-asides may be established. A set-aside is a procurement technique which limits solicitation of bids or proposals to certain types of firms, for example, minority business firms. In every case adequate competition must be obtained with award being made to the lowest, responsive, responsible bidder or to the proposer in non-advertised procurement submittinq the most advantageous proposal. PART V MBE Responsibilities for Prime Contractor% Within 1S days after contract award the prime contractors are required to submit to the grantee a detailed MBE participation-~lan contatntno an MBE goal and procedures for achievtnq that qoal'. This submission must also include a detailed list of all MBE firms to be utilized in achiev- ing the goal. All prime contractors on EPA construction ~rant ~rojects are exnected to make the following efforts to achi~e the use of minority-owned firms to the maximum extent practical on the project: MBER - 9 of 26 -10- 1. Extend opportunities for joint arrangements or subcontracting and purchasing to minority-owned firms. 2. Comply with MI~IORITY BUSINESS ENTERPRISE PARTICIPATION 8ID SPECI- FICATION (See Appendix I and Appendix II). 3. Take affirmative steps to ensure compliance with the EPA regula- tions. These steps include, but are not limited to: a. Compiling and submitting to the grantee for submission to the Director, Office of Civil Rights and Urban Policy, USEPA, Region II, a list of minority engineering and construction contractors to be utilized through joint arrangement or sub- contracting. b. Preparing a list of minority contractors contacted and awards made to minority-owned firms, and setting forth specific ef- forts made to identify and award contracts to such firms. Full documentation of such efforts must be made available to the grantee for submission to the Office of Civil Rights and Urban Policy upon request. 4. Require subcontractors under the contract to comply with the pro- visions of the contract and the affirmative steps for goal achieve- merit stated in these procedures. 5. Maintain records show~ng procedures which have been adopted to comply with EPA policy. 6. Keep grantee's MBE Officer informed of all contracts and subcon- tracts awarded to MSEs or changes in plans to award previously reported subcontracts. The actual attainment of the established goal shall be prima facie evidence of positive efforts and shall release the contractor from any further burden of proof of positive efforts. Contractors are, however, cautioned to nevertheless maintain adequate records because the subsequent withdrawal of a minority firm from a subcontract could reduce the con- tractor's MBE participation below an acceptable level and subject him to a requirement of objective demonstration of positive efforts. Where a contractor is unable to meet the required MBE goal o objective demon- stration of positive efforts must include, but are not limited to the following five (5) steps, inclusive of the requirements for records which must be maintained to docuni~nt the contractor's efforts: ' MBER 10 of 26 -ll- The contractor must extend opportunities to MBEs, such as by adver- tising in minority trade association newsletters and minority-owned media. The bid due date and reasonable MBE response due date must be specified in the advertisement. The publications chosen must be distributed within reasonable proximity of the location of the con- struction project. The advertisement must be for specific sub- contracts which are described in reasonable detail. TO DEMONSTRATE COMPLIANCE - Have available for grantee's MBE Officer copies of all written eftorts to extend opportunities to MBEs including all advertisements which appeared in minority publications, including the name and address of the publication, the date on which the advertisement appeared, and the audience at which the publica- tion is directed {i.e., whether general audience publication or special MBE contractor publication). The contractor must notify all minority contractor associations known to him of the available subcontracting opportunities. The minority associations so notified shall include as a minimum the local Office of Minority Business Enterprise (OMBE) and Minority Contractor Assistance Center {MCAC), and all contractor associations identified to the contractor by the USEPA, Region II, Office of Civil Rights and Urban Policy. The notification must be by certi- fied mail and should be received by the addressee associations in time to permit effective MBE participation. The NBE response due date must be specified in the notifications. The solicitation must be for specific subcontracts and the work to be done must be described as ac~rately as possible and in reasonable detail. TO DEMONSTRATE COMPLIANCE - Have available for grantee's MBE Officer copies of all letters or other communications, including enclosures and attachments which were sent to minority contractor associations. Include name, address, and date of mailing for each letter sent. Have available copies of all correspondence and a record {e.g., log) of all telephone replies received in response to the solicitations. The record of telephone responses should include the date and time of the incoming call and the date{s) and time(s) it was returned. Contractors must respond promptly to both telephone and mail responses from MBE associations and firms as protracted delays in responding MBER - 11 of 26 -12- will be interpreted by the Office of Civil Rights and Urban Policy as an attempt to discourage MBE participation. Be able to document follow-up steps taken by contractor. Where technically feasible, the contractor should segment the work to be contracted to accommodate the size and capabilities of avail- able minority subcontractors. This procedure is essential to assure that MBEs are provided equitable sHbcontracting opportunities. TO DEMONSTRATE COMPLIANCE - Have available for grantee's MBE Officer documentation which objectively demonstrates the capabilities of available minority business enterprise construction subcontractors in the general area of the location of the construction project 6r in areas reasonably proximate thereto. The contractor must be knowledgeable concerning information regarding MBE capabilities which is readily available from local minority contractor associa- tions, local OMBE Office, local MCAC Office, and the EPA, Region II, Office of Civil Rights and Urban Policy. Objectively demonstrate by appropriate documentation that a concerted attempt was made by the contractor to segment the subcontract work in ways that accom- modated the size and capabilities of the known available MBEs. The contractor must send solicitation letters by certified mail inviting quotes or proposals from individual minority business enterprises, The solicitation letter must reference specifically segmented portions of work to be subcontracted. The portions of work must be described as specifically and accurately as possible. Inquiries for further details should be encouraged. Letters that are general and do not describe specifically the portions of work for which quotes are desired are not acceptable, as such letters do not generally bring responses. The solicitation letter must be sent in a timely manner so as to allow minority firms sufficient opportunity to develop quotes or proposals for the work described. In general, such solicitation letters must be postmarked no later than fifteen (15) days before proposals are due, whether the solicitation is being made before bids or proposals are submitted or during the performance of the prime contract. All solicitation letters should include the bid date and a response due date for the information of the addressee. Contractors are also strongly encouraged to follow up such letters with telephone calls to determine the degree of interest the minority firms have in the work. ~ DEMONSTRATE COMPLIANCE - Have available for grantee's MBE Officer copies of all soliciation let]iers and a list of all parties to whom MBER - 12 of 26 -13- each letter was sent, including name, mailing address, and type of business in which the company is known to be engaged. Have available all reply letters and log of all reply telephone calls. Be able to demonstrate objectively what action contractor took in response to each reply. Also, have available a log of any follow-up telephone calls by contractors to letter recipients who did not respond. Where an MBE submits a proposal for a subcontract to a contractor, and the MBE proposal is deemed unreasonably high and is rejecteO for that reason, then, to demonstrate good faith, the contractor must engage in direct negotiations with the MBE in an attempt to reach a mutually acceptable price. This requirement is not appli- cable to those cases where an MBE proposal is rejected in favor of another MSE. TO DEMONSTRATE COMPLIANCE - Have available for grantee's MBE Officer ~ecords which show that negotiation meetings took place, including time, date and place of each conversation and meeting; name and address of MBE; specific and accurate description of the segment of work which was the subject of the negotiation; and approximate estimated dollar value of the subcontract segment. Where the MBE negotiation was unsuccessful due to failure to agree on price, the contractor must be able to demonstrate, by the production of appro- priate document, that the subcontractor selected for the segment was lower than the MBE and that the work segment so contracted was the same work segment under negotiation with the MBE, and not a reduced portion thereof. The degree of goal attainment by minority-majority joint ventures, minority contractors, and minority suppliers should be calculated as follows: A joint venture consisting of minority and majority business enterprises, functioning as a prime contractor, will be credited with minority parti- cipation on the basis of percentage of the dollar amount of the work to be performed by the MBE. For example, if a minority-majority joint venture proposes to perform 50% of a project quoted at $500,000 and 50% of the work is to be performed by the minority partner in the joint venture, minority participation will be credited as 25% of'the work or $125,000. MBE contractors will be credited with minority participation for that portion of the contract which they j!erform and that portion subcontracted to minority firms. For example, if an MBE contractor proposes to perform 50% of a project quoted at $500,000 and subcontracts an additional 25% to a minority firm, minority participation will be credited at 75% or $375,000. MBER - 13 of 26 PROPOSAL SPECIFICATION MINORITY BUSINESS ENTERPRISE PARTICIPATION APPENDIX I CONSULTANT FIRM RESPONSIBILITIES The following notice must be included in all solicitations for pro- posals for architectural and engineering work on all projects that receive EPA funding for the construction or,upgrading of wastewater treatment facilities or adjuncts thereto. Goals for MBE proqram It is the policy of the Federal Government that minority businesses shall have the maximum feasible opportunity to participate in the performance of contracts performed under Federal grants-in-aid program. The consultant agrees to use his best efforts to carry out this policy through award of contracts and subcontracts to minority business enter- prises to the fullest extent, consistent with the efficient performance of this contract. As used in this contract, the term "minority busi- ness'' means a business at least 51 percent of which is owned and controlled by minority group members, or, in the case of a publicly- owned business, at least 51 percent of the stock of which is owned and controlled by minority group members. For the purpose of this definition, minority group members are Black Americans, Hispanic Americans, Asian Americans, American Indians, American Eskimos, and American Aleuts. The minority ownership must exercise actual day- to-day management. Each consultant must fully comply with the requirements, terms and conditions of the attached U.S. Environmental Protection Agency, Region II Minority Business Enterprise (MBE) requirements and the attached statement of EPA policy of December 26, 1978 (43 Federal Register 60220-60224) including the goals established for minority business participation during the performance of this contract. The consultant commits himself to the.performance of positive efforts to achieve the goals for minority business participation contained therein and all other requirements, terms and conditions of the bid specifications by submitting a properly signed bid or proposal. MBER - 14 of 26 [-2 A consultant who does not objectively demonstrate in his proposal the required positive efforts (i.e., attempted to achieve the Region [t goals by contacting minority consultants in an effort to engage them) wil! not, for this reason alone, have his contract proposal rejected as non-responsive. In the event such a consultant is recommended for contract award by the grantee, the Director of the Office of Civil Rights and Urban Policy (OCRUP) will inform the grantee, in writing, of the prospective consultant's non-compliance and the basis for such determination. The consultant will be given an opportunity to explain in writing, or at a conference, if requested, the reasons for non-compliance with the required positive efforts. If the reasons for non-compliance are unsatisfactory, the consultant will be requested, in writing, to make additional positive efforts to utilize minority firms prior to contract award. The determination of compliance or non-compliance with the positive efforts requirement will include consideration of the following: 1. Whether the goal has been met on a given contract. 2. If the goal has not been met, the extent to.which the consultant attempted to: a. Identify candidate Minority Business Enterprises. b. Contact candidate Minority Business Enterprises. Solicit proposals from candidate Minority Business Enterprises and any response thereto, and the basis of evaluation of any Minority Business Enterprise proposals received. Any other evidence relevant to the good faith efforts of the consultant to comply. Consultant Firm Non-Compliance If after fifteen (15) days of contract award the consultant's efforts remain unsatisfactory to the grantee and/or the Director of the Office of Civil Rights and Urban Policy, either of the following steps must be taken: 1. Documentation to the grantee and the Director of the Office of Civil Rights and Urban Policy explaining the reasons for non-utilization of MBEs. MBER - 15 of 26 I-3 2. Request a conference with the grantee and the Regional Director of the Office of Civil Rights and Urban Policy for guidance on possible corrective actions which may be taken in order to comply with MBE obligations. Thirty days after the consultant has been notified to make additional positive efforts, such consultants may after documentation procedures or opportunity for conference, be subject to appropriate sanctions, in accordance with the attached EPA policy. Consultant will %e required to execute and submit to the grantee's MBE Officer copies of all subcontracts and purchase orders with minority-owned firms within fifteen (15) days after contract award. In the event a consultant fails to utilize the minority-owned firms indicated in his proposal and/or in the subcontracts and purchase orders, he will be expected to explain the reasons for non-utilization to the grantee and the EPA Region II, OCRUP. If there is non-utilization without good cause, the grantee will be expected to require corrective efforts by the consultant. Failure on the part of the grantee to require such efforts or failure to enforce these procedures may result in the refusal of EPA to make contract payment. In very limited situations where circumstances otherwise justify approval of a contract to a consultant which has not satisfactorily complied with the positive efforts requirements {e.g., sole consultant, where delay incident to resolicitation will cause substantial harm to the grantee), the EPA in its discretion may concur in the recommended award conditioned upon the inclusion of satisfactory contract pro- visions which require: 1. Specific and defined positive efforts toward minority business utilization during contract performance; and/or 2. The withholding of progress payments until such time as the positive effort requirements have been satisfactorily complied with and approved by the grantee and the Director of the Office of Civil Rights and Urban Policy, Region II. MBER 16 of 26 BID SPECIFICATION MINORITY BUSINESS ENTERPRISE PARTICIPATION APPENDIX II PRIME CONSTRUCTION CONTRACTOR RESPONSIBILITIES The following notice must be included in all invitations and other solicitations for bids and proposals for construction work on all projects that receive EPA funding for the construction or upgrading of wastewater treatment facilities or adjuncts thereto. Goals for MBE Proqram It is the policy of the Federal Government that minority businesses shall have the maximum feasible opportunity to participate in the performance of contracts performed under Federal grants-in-aid program. The contractor agrees to use his best efforts to carry out this policy through award of contracts and subcontracts to minority business enter- prises to the fullest extent, consistent with the efficient performance of this contract. As used in this contract, the term "minority business" means a business at least 51 percent of which is owned and controlled by minority group members; or, in the case of a publicly-owned business, at least 51 percent of the stock'of which is owned and controlled by minority group members. For the purpose of this definition, minority group members are Black Americans, Hispanic Americans, Asian Americans, American Indians, American Eskimos, and American Aleuts. The minority ownership must exercise actual day-to-day management. Each contractor must fully comply with the requirements, terms and conditions of the attached U.S. Environmental Protection Agency, Region II Minority Business Enterprise (MBE) requirements and the attached statement of EPA policy of December 26, 1978 ~43 Federal Register 60220-60224) including the goals established for minority business participation during the performance of this contract. The contractor con. its himself to the performance of positive efforts to achieve the goa)s for minority business participation contained there- in and all other requirements, terms and conditions of the bid specifications by submitting ~ properly signed bid. The contractor will appoint a company executive to assume the responsi- bility for the implementation of s~ch requirements, terms and conditions. MBER - 17 of 26 II-Z The prime contractor agrees that he will make good faith efforts to subcontract at least .te_~_~J_lJ_)_Percent of the total value of this contract to minority bus,ness. Failure to attain this percentage or demonstrate positive efforts to do so may lead to withholding of contract payment, a finding of non-responsibility or other sanctions, in accordance with the attached EPA policy. For the purpose of this program, the term "subcontract" includes all agree- merits for construction, modification and service work and supplies contracted for by the prime contractor in the prosecution of the work under his contract. Although it is not made a requirement herein for EPA approval of a contract that a contractor in fact meet or exceed these goals in its contracting, the contractor will be required to objectively demonstrate to the grantee and to EPA, Region II, Civil Rights and Urban Policy Director prior to contract approval and also during contract performance that he has exerted positive efforts to meet these goals. Notwithstanding the fact that a contractor may have the capability to complete the total project with his own work- force and without the use of subcontractors, each contractor will still be required to take positive efforts to subcontract to minority firms a share of the work consistent with the goals. These require- merits are also applicable to bidders who are themselves minority- owned enterprises. MBE Studies, S~ur~vveys~ and Reports 1. The contractor shall cooperate with the grantee and the EPA Region II, Civil Rights and Urban Policy Director in studies and surveys of the contractor's minority business procedures and practices. 2. The contractor shall maintain records showing, (al awards to minority businesses; and {b) specific efforts to identify and award subcontracts to minority businesses. 3. The contractor shall submit periodic reports of subcontract- ing to known minority businesses in such form and manner and at such time {not more often than quarterly) as the grantee or the EPA, Region II, Civil Rights and Urban Policy Director may prescribe. Specific Good Faith Efforts The contractor shall be deemed to be in compliance with the require- merits, terms and conditions of the U.S. Environmental Protection Agency, Region II, Minority Business Enterprise Policy and Program if he meets or exceeds its conmitment to the goals for minority business participation in its subcontracts and subagreements. MBER 18 of 26 II-3 The contractor's commitment to the goals for minority business partici- pation as required by the U.S. Environmental Protection Agency, Region II, Minority 'Business Enterprise Policy and Program, constitutes a commitment that he will make every good faith effort to meet such goals. No con- tractor shall be found to be in noncompliance solely on account of the contractor's failure to meet his goals. BUt he shall be given the opportunity to objectively demonstrate to the grantee and the EPA, Region II, Office of Civil Rights and Urban Policy Director, that he has instituted all the specific affirmative action steps specified in the USEPA, Region II, MBE Policy and Program and made every good faith effort to make these steps work toward the attainment of his designated goals of allowing minority business enterprises maximum feasible opportunity to participate in subcontracts and subagreements under this EPA funded project. Contractors who fail to achieve the goal and fail to institute the good faith effort steps specified in this appendix may be found non-responsible or be subject to contractual sanctions. Where the Director of the Office of Civil Rights and Urban Policy makes such a determination, the grantee will be informed that EPA will withhold grant payment if the non-responsible contractor fails to take corrective action on deficiencies or to explain satis- factorily why such action cannot be taken. Contractor Non-C_L~liance Contractors who fail to achieve their commitments to the goals for minority business participation must have engaged in affirmative participation, which is supported by documentation at least as extensive as the following: 1. Documentation of efforts to extend opportunities to MBEs such as advertisement in minority trade association newsletters and minority-owned media no less than fifteen (15) days before MBE responses are due for specific subcontracting that would be anticipated to result at least in a degree of )(BE partici- pation equal to the percentage goal for MBE utilization specified for the contract. 2.

Copies of solicitation letters inviting quotes or proposals from minority business enterprise, segmenting portions of the work and specifically describing, as accurately as possible, the portions of the work for which quotes or pro- posals are solicited from minroity firms and encouraging inquiries for further details. Letters that are general and do not describe specifically the portions of work for which quotes or proposals are desired are not acceptable, as such letters generally do not bring responses. Such letters will be sent in a timely manner so as to allow minority firms sufficient opportunity to develop quotes or proposals for the work described. In general, such solicitation letters shouldbe postmarked no later than fifteen (15) days before MBE responses are due. 5. Documentation of good faith negotiation with those MBEs from whom responses were received in an effort to reach a mutually acceptable price. Where the MBE participation was unsuccessful due to failure to agree on price, the bidder must document that the subcontractor selected for the work segment was lower than the MBE and that the work segment so contracted was the same work segment under negotiations with the MBE, and not a reduced portion thereof.

Room E-315, Wuhin~'~on. D.C. 20460. There are about 200 species of white ~rubs, some completing their life cycle in one year and some in four, with a three-year cycle most conunon. White gr~bs overwtnter in the soil. both as adults &nd Ls larvae. The latter feed tn they work their way down into the soil usually below the frost line? Adults, the June b.-etle, emel~e from the soil tn the spring and feed on the foliage According to the ~ppllc~nt. the white irub has infested land to be planted with wheat in Al/alii. Blaine, Cotton. Dewey, Ellis, Garfield. Oraflt, KAy. Kingfisher. Major. Washits. Woods. and Woodward Counties. The three white frubs per squire foot will destroy most of the emerLdng wheat: square foot arc common. The Appli- cant also claimed that it will be neces- sary to replant a considerable amount ol acreage in the alfected counties due to de~nage already inflicted. The acre- age involved hss the potential of pro- ductng over $,375.000 bushels ol hard red winter wheat that h~s a current value o[ $16,931,250. There ts no other pesticide registered for the control of this pest. The Applicant proposes to use two formulations of Diaztnon (0,0-diethyl 04 2.isopropyl-6-met hyl-4-pyrlmldtnyl } phnsphorothioateL A total of 430,000 pounds active ingredient ia.L) will be applied by ground equipment and in- corporated into the roll. The Appil- cant states that chemical treatment with D[~Jnon of white grub-Infested wheat land mu~t be made prior to planting winter wheat. No detectable residues (less than 0.03 part, per million (ppm). method sensitivity) are anticipated from the proposed ~e. Since this pesticide is extremely toxic to wildlife and fish, its use ts restricted to ~round application only and it must be kept out of bodies of water. After reviewing the application and other available information. EPA has determined that Ca) a pest outbreak of white grub has occurred: Cbl there ts no pesticide presently registered and available for use to control the white grub tn Oklahoma; ¢c) there are no al- ternative me.ns of control taking into account the efficacy and ha"~rd; id) significant economic problem.~ may result If the white grob is not con- trolled; and les the time available for action to mitigate the problems ~osed is Lruufficient for a pesticide to be reg- istered for this use. Accordingly. the Applicant hu been granted a specific exemption to use the pesticide noted above until December 15, 19';8. The Specific exemption ts also subject to the following conditions: 1. A total of 430.000 pounds a.i. of the products Dlasinon 140 and Dia- zinon AOS00 may be used; 2. Dlf.~non may be applied in the counties mentioned above: 3. The do~age rate shall not exceed ? to 14 pounds per acre of Oia~tnon 14(], or IV~ quarts per acre of Disztnon AG$00; 4. A single application may be made; 5. Applications must be restricted to r~ound equipment only; 6. DiarJnon must be soil incor~p6rat- ed [mmedletely after application: '/. Turn areu or row ends must be 8.

The backfill shall be solidly compacted under and around the pipe with mechanical tampers or other proper tools designed for the pur- pose. The tamping shall not be excessive so as to raise the pipe, how- ever, it shall provide a firm, .continuous support for the pipe. The backfill, to a height of one foot (1') above the top of the pipe, shall be selected materials carefully deposited by hand shoveling and tamping and not pushed into the trench by heavy equipment. Where the material removed from the trench shall not be considered suitable to serve as select material to support the pipe, in the opinion of the Engineer, select material, as described in the section entitled, ADDITIONAL BACKFILL, shall be used as directed by the Engineer. The remainder of the trench shall be backfilled with select mate- rial deposited in not over 8-inch layers and solidly tamped with mechani- cal tampers or proper tools designed for the purpose. The Engineer may, at his discretion, direct the contractor to add, at no extra cost, suf- ficient water during tamping to assure a complete consolidation of the backfllled earth. No stone weighing over 25-pounds shall be used in any portion of the refilling, and all stones shall be distributed and alternated with earth filling in such a manner that all interstices between them shall be filled with earth. Frozen earth shall not be used for refilling.
