<br />Chapter 3 <br />PROCEDURES FOR PLAN APPROVAL <br />While responding promptly to each request for a ventilation plan approval is an important <br />part of the review process, review quality and thoroughness are utmost in importance. Al] <br />districts should follow similar standard operating procedures to accomplish an expeditious <br />and efficient review. The basic procedures are as follows: <br />A. All requests for approval of ventilation plans or revisions thereof should be <br />submitted to the district office. Districts that desire an arrangement for mine <br />operators to submit plans to other locations should obtain approval of these other <br />locations by the Administrator. <br />B. The progress of the plan through the approval process should be coordinated by <br />the Engineering Coordinator/ Chief of Engineering Services. Plan or revision <br />requests should be handled efficiently with an effort to complete all requests of any <br />proposed plan, revision, or change in a time period of 45 calendar days. <br /> <br /> <br /> <br />L <br />1 <br /> <br /> <br />C. The supervising ventilation specialist or the ventilation subordinates will critically <br />review the plan as follows: <br />1. The information to be included on the map is listed in 30 CFR 75.372. The <br />maps should be reviewed against the standard to ensure that all the basic <br />information is shown. In addition to a mechanical review of the listed <br />items, the reviewer should apply his (her) expertise to ensure that the <br />current and projected systems are viable and reliable. It is important to <br />note that only that portion of the map which contains information required <br />under 30 CFR 75.371 will be subject to approval by the district manager. <br />2. Determine that information required by 30 CFR 75.371 has been submitted. <br />The plan needs to contain only the particular air flow, methane, and dust <br />control measures necessary to address the unique conditions at the mine. <br />Circumstances referred to in 75.371, but not present in the mine, do not <br />need to be addressed. The ventilation regulations are structured to require <br />in the plan only those standards which differ from requirements listed in the <br />applicable standards. For example, an air quantity should be specified in <br />the plan only if the quantity required at the intake to longwall sections is <br />different from that specified in 30 CFR 75.325(c), 30,000 c&n. <br />3. Written comments from representatives of miners should be considered in <br />the review process. <br />4. Ensure that the plan does not contain any statements which are inconsistent <br />with existing mandatory regulations. The reviewer must be cognizant of <br />this potential problem to avoid approving a plan containing a provision that <br /> <br />i <br />LJ <br />Lei <br /> <br /> <br /> <br /> <br /> <br /> <br />
