PROCEDURE INSTRUCTION LETTER NO. I19-V-01
FROM: TIMOTHY R. WATKINS
Administrator for
Mine Safety and Health Enforcement
SUBJECT: Procedure for Permitting the Use of Belt Air to Ventilate Working Sections of Underground Coal Mines
Scope
This Procedure Instruction Letter (PIL) applies to Coal Mine Safety and Health (CMS&H) District Managers, Supervisors, Specialists, and Inspectors.
Purpose
This PIL provides instruction for district personnel regarding the procedures for permitting the use of belt air to ventilate the working sections of underground coal mines. This PIL replaces PIL I12-V-14.
Procedure Instructions
When evaluated and approved by the District Manager in a mine ventilation plan, air from a belt air course may be used to ventilate a working section. MSHA will conduct at least one on-site investigation (a) at any mine proposing to use belt air to ventilate the working section, prior to authorizing such use, and (b) at any mine that has already received authorization to use belt air to ventilate the working section, if that mine has not previously been subject to an on-site investigation in relation to the use of belt air.
Any mine requesting approval to use belt air to ventilate the working section must maintain the level of safety, and therefore not reduce protections currently afforded miners in underground mines while implementing advances in mining technology. In addition, the operator must comply with the requirements of 30 CFR §75.350(b)(1)-(8).
Background
Section 75.350(b) permits the use of air from a belt air course to ventilate a working section when evaluated and approved by the District Manager in the mine ventilation plan. This PIL is intended to ensure that, prior to permitting the use of belt air to ventilate working sections or continuing the practice after a prior approval, MSHA will have conducted at least one on-site investigation into the safety and health implications of the mine's proposed ventilation system, and that the investigation be conducted by an individual qualified to make the necessary findings to support an appropriate conclusion by the District Manager.
Authority
Federal Mine Safety and Health Act of 1977, as amended, 30 USC § 801, et seq.; 30 CFR §§ 75.323(b) and 75.350(b).
