Determinations. The National Processing Center will determine the appropriate prevailing wage as follows:
(1) Except as provided in paragraphs (e) and (f) of this section, if the job opportunity is covered by a collective bargaining agreement (CBA) that was negotiated at arms-length between the union and the employer, the wage rate set forth in the CBA agreement is considered as not adversely affecting the wages of U.S. workers similarly employed, that is, it is considered the “prevailing wage” for labor certification purposes.
(2) If the job opportunity is not covered by a CBA, the prevailing wage for labor certification purposes shall be the arithmetic mean, except as provided in paragraph (b)(3) of this section, of the wages of workers similarly employed in the area of intended employment. The wage component of the DOL Occupational Employment Statistics Survey shall be used to determine the arithmetic mean, unless the employer provides an acceptable survey under paragraph (g) of this section.
(3) If the employer provides a survey acceptable under paragraph (g) of this section that provides a median and does not provide an arithmetic mean, the prevailing wage applicable to the employer's job opportunity shall be the median of the wages of workers similarly employed in the area of intended employment.
(4) The employer may utilize a current wage determination in the area under the Davis-Bacon Act, 40 U.S.C. 276a et seq., 29 CFR part 1, or the McNamara-O'Hara Service Contract Act, 41 U.S.C. 351 et seq.
(c) Validity period. The National Processing Center must specify the validity period of the prevailing wage, which in no event may be less than 90 days or more than 1 year from the determination date. To use a prevailing wage rate provided by the NPC, employers must file their applications or begin the recruitment period required by §§ 656.17(e) or 656.21 of this part within the validity period specified by the NPC.
(d) Similarly employed. For purposes of this section, similarly employed means having substantially comparable jobs in the occupational category in the area of intended employment, except that, if a representative sample of workers in the occupational category can not be obtained in the area of intended employment, similarly employed means:
(1) Having jobs requiring a substantially similar level of skills within the area of intended employment; or
(2) If there are no substantially comparable jobs in the area of intended employment, having substantially comparable jobs with employers outside of the area of intended employment.


20 CFR § 656.40

Scoping language

Application process. The employer must request a PWD from the NPC, on a form or in a manner prescribed by OFLC. Prior to January 1, 2010, the SWA having jurisdiction over the area of intended employment shall continue to receive and process prevailing wage determination requests in accordance with the regulatory provisions and Department guidance in effect prior to January 1, 2009. On or after January 1, 2010, the NPC shall receive and process prevailing wage determination requests in accordance with these regulations and with Department guidance. The NPC will provide the employer with an appropriate prevailing wage rate. The NPC shall determine the wage in accordance with sec. 212(t) of the INA. Unless the employer chooses to appeal the center's PWD under 656.41(a) of this part, it files the Application for Permanent Employment Certification either electronically or by mail with the processing center of jurisdiction and maintains the PWD in its files. The determination shall be submitted to the CO, if requested.
