2. The application of such standard to such mine will result in a diminution of safety to the miners in such mine.
In addition, the regulations at 30 CFR
44.10 and 44.11 establish the requirements for filing petitions for modification.
II. Petition for Modification Docket Number: M2021002C.
Petitioner: Blue Mountain Energy, Inc., 3607 County Road 65, Rangely, Colorado ZIP 81648.
Mine: Deserado Mine, MSHA ID No.
0503505, located in Rio Blanco County, Colorado.
Regulation Affected: 30 CFR 75.507
1a Electric equipment other than power-connection points; outby the last open crosscut; return air; permissibility requirements.
Modification Request: The petitioner requests a modification of the existing standard, 30 CFR 75.5071a Electric equipment other than power-connection points; outby the last open crosscut;
return air; permissibility requirements.
Specifically, the petitioner is applying to utilize the battery-powered CleanSpace Powered Respirator in the Deserado Mine in Colorado in return air outby the last open crosscut.
The petitioner states that:
a Blue Mountain Energy currently uses the 3M Airstream helmet to provide additional protection for its miners against exposure to respirable coal mine dust.
b For more than 40 years the 3M
Airstream Headgear-Mounted Powered Air Purifying Respirator PAPR System has been used by many mine operators to help protect their workers. Recently 3M indicated they faced multiple key component supply disruptions for the Airstream product line, which made it difficult to provide acceptable supply service levels. Because of these issues, 3M discontinued the Airstream on or before June 1, 2020. 3M further announced that February 2020 was the final date to place an order for systems and components and that June 2020 was the final date to purchase Airstream components.
c Following that discontinuation, mines using the 3M Airstream do not have an MSHA-approved alternative PAPR to provide to miners.
d Currently there are no replacement of 3M PAPRs that meet MSHA
standards for permissibility. Under 30
CFR, electronic equipment must be approved by MSHA to be used in underground mines with potentially explosive atmospheres.
e A benefit of using PAPRs is that they provide a constant flow of air inside the headtop or helmet, offering

miners both respiratory protection and comfort in hot working environments.
f Another manufacturer offers an alternative product for other environments and applicationsthe CleanSpace EX Powered Respirator.
However, the CleanSpace EX Powered Respirator is not MSHA-approved as permissible, and the manufacturer is not pursuing MSHA approval.
g The CleanSpace EX Powered Respirator is intrinsically safe and meets International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres IECEx approval standards for quality assurance and protection.
h The product provides an equivalent level of respiratory protection in underground mining environments.
The petitioner proposes the following alternative method:
a The petitioner will use the CleanSpace EX Powered Respirator in return air outby the last open crosscut.
b The equipment shall be examined at least weekly by a qualified person as defined in 30 CFR 75.5122; the examination results shall be recorded weekly. Examination entries may be expunged after one year.
c The petitioner shall comply with 30 CFR 75.323.
d A qualified person as defined in 30 CFR 75.151 shall monitor methane for the subject area of the mine as required by the mandatory standards.
e All qualified persons and miners affected shall receive specific training on the terms and conditions of the Decision and Order before using the equipment in the affected area. A record of any training on this Decision and Order shall be kept and provided upon request by an Authorized Representative.
f Within 60 days of the Decision and Order issued by MSHA becoming final, the mine operator shall submit proposed revisions for its approved 30 CFR 75.370
mine ventilation plan and approved 30
CFR part 48 training plan to the Coal Mine Safety and Health District Manager. These proposed revisions shall specify how the operator will provide initial and refresher training in compliance with the terms and conditions stated in MSHAs Decision and Order. When training is conducted, a MSHA Certificate of Training Form 500023 shall be completed. Comments shall be included on the Certificate of Training indicating that the training was the use of nonpermissible testing equipment.
g The mine operator shall be responsible for determining that all

persons including contractors are using the equipment in accordance with MSHAs Decision and Order.
h The mine operator shall post this Decision and Order in unobstructed locations on the bulletin boards and/or in other conspicuous places where notices to miners are ordinarily posted for a period of not less than 60
consecutive days.
The petitioner asserts that the alternate method proposed will at all times guarantee no less than the same measure of protection afforded the miners under the mandatory standard.
Docket Number: M2021003C.
Petitioner: Blue Mountain Energy, Inc., 3607 County Road 65, Rangely, Colorado ZIP 81648.
Mine: Deserado Mine, MSHA ID No.
0503505, located in Rio Blanco County, Colorado.
Regulation Affected: 30 CFR 75.500d Permissible electric equipment.
Modification Request: The petitioner requests a modification of the existing standard, 30 CFR 75.500d, as it relates to the use of an alternative method of respirable dust protection in the Deserado Mine in Colorado.
Specifically, the petitioner is applying to use a battery powered respirable protection unit called CleanSpace EX
Powered Respirator in or inby the last open crosscut.
The petitioner states that:
a Blue Mountain Energy currently uses the 3M Airstream helmet to provide additional protection for its miners against exposure to respirable coal mine dust.
b For more than 40 years the 3M
Airstream Headgear-Mounted Powered Air Purifying Respirator PAPR System has been used by many mine operators to help protect their workers.

c Following that discontinuation, mines using the 3M Airstream do not have an MSHA-approved alternative PAPR to provide to miners.
d Currently there are no 3M
replacement PAPRs that meet MSHA
standards for permissibility. Under 30
CFR, electronic equipment must be approved by MSHA to be used in underground mines with potentially explosive atmospheres.
