§37.3. Chest radiographs required for miners. — Inbound Citations

(c) All examinations given or arranged by the Secretary will comply with the time requirements of § 37.3. Whenever the Secretary gives or arranges for the examinations of miners at a time, a written notice of the arrangements will be sent to the operator who must post the notice on the mine bulletin board.

(3) The proposed beginning and ending date of the 6-month period(s) for voluntary radiography exams and spirometry tests (see §§ 37.3(a) and 37.92(a)), the estimated number of miners to be given or offered examinations during the 6-month period under the plan, and a roster specifying the names and current home mailing addresses of each miner covered by the plan;

(g) Upon notification from NIOSH that sufficient time has elapsed since the previous period of examinations, the operator must resubmit a plan for each of its coal mines to NIOSH for approval for the next period of examinations (see §§ 37.3(a)(2) and 37.92(a)). The plan must include the proposed beginning and ending dates of the next period of examinations and all information required by paragraph (b) of this section.

(ii) One or more alternate non-mobile approved medical examination facilities for the reexamination of miners and for the mandatory examination of miners when necessary (see §§ 37.3(b) and 37.92(b)), or an assurance that the mobile facility will return to the location(s) specified in the plan as frequently as necessary to provide for medical surveillance examinations in accordance with these regulations.

(3) A third spirometry test and respiratory assessment will be provided no later than 2 years after the tests in paragraphs § 37.3(b)(2) and paragraph (b)(2) of this section if the chest radiograph shows evidence of pneumoconiosis as defined in § 37.3(b)(3) or if the second spirometry test results demonstrate a 15 percent or greater decline in the percent predicted FEV1 value since the initial (i.e., baseline) test.

(i) Percent predicted FEV1 will be calculated according to prediction equations published in Spirometric Reference Values from a Sample of the General U.S. Population, American Journal of Respiratory and Critical Care Medicine, 159(1):179-187, January 1999 (incorporated by reference, see § 37.98).

(ii) A correction factor to Caucasian reference values will be applied when testing individuals of Asian descent as specified in the ATS Technical Standards: Spirometry in the Occupational Setting, p. 987 (incorporated by reference, see § 37.98).

(3) A third spirometry test and respiratory assessment will be provided no later than 2 years after the tests in paragraphs § 37.3(b)(2) and paragraph (b)(2) of this section if the chest radiograph shows evidence of pneumoconiosis as defined in § 37.3(b)(3) or if the second spirometry test results demonstrate a 15 percent or greater decline in the percent predicted FEV1 value since the initial (i.e., baseline) test.
