If the MSHA district office determines that the modification constitutes a hazard due to the particular mine environment in which the machine(s) will operate, or the Field Modification Request is not in compliance with the applicable provisions of 30 CFR, Parts 57 or 75, the district office will notify A&CC that the request should not be accepted. (See Appendix 1, Enclosure F for sample.) 5.7. Acceptance 5.7.1. If the application is determined by A&CC to meet all applicable requirements, a letter of Field Modification Acceptance will be sent to the applicant. An invoice for the total cost of the investigation will then follow. Copies of the notification will also be sent to the district office. 5.8. Additional Modifications 5.8.1. An applicant is not required to submit a Field Modification Request to A&CC for certain modifications. In these cases, the applicant must notify the MSHA district office in writing of the changes. Inspection of the modification may be made at the discretion of the district manager. A copy of all notifications should be maintained in the appropriate mine file. Field modification requests that don’t require a request to the A&CC include: 5.8.1.1. Addition of methane monitors (excluding methane monitors that tie into the shutdown systems of diesel equipment) 5.8.1.2. Field modifications duplicating the original equipment manufacturer's approved design of an essentially identical machine. For example, a shuttle car with approval number 2G-2000-0 may have been originally approved without an emergency stop switch. Subsequently, the manufacturer filed an application and received approval from A&CC to install a specific switch, X/P-1000-0 on all new shuttle cars. These shuttle cars would bear Approval Number 2G-2000-1, or the first extension of the original approval. An operator owning a shuttle car with the original approval 2G-2000-0 and wishing to add an emergency stop switch can contact the manufacturer.

Field modifications duplicating previously accepted field changes for machines of the same type and with the same approval number at the same mine or under the direction of the same maintenance supervisor(s). 5.8.1.4. Installation of silicon diode grounding equipment in existing explosionproof enclosures on machines, provided no cable gland openings are made in the machine and provided the installation meets the requirements of 30 CFR 75.703-3(d) which refers to voltage and current ratings, and over current protection for such devices. 5.8.1.5. Removal of non-safety-related electrical components from a machine. For example, relocation of the headlight resistors to the machine control box would eliminate the headlight resistor enclosures. All unused cable entrances must be plugged, and plugs must be secured in place in accordance with Part 18 requirements. 5.8.1.6. Changes that are made within explosion-proof enclosures and do not conflict with permissibility requirements. Circuit breakers, overload relays, and fuse protection must be maintained as originally approved. 5.8.1.7. Change of trailing cables on machines with cable reels having external trailing cable connections from flat to round or vice versa, from a G to GGC or vice versa, and changes to a larger cable size, provided the insulated trailing cable strain clamp still grips the cable properly and provided no changes are made to the cable entrance glands. 5.8.1.8. Change of trailing cable from G to G-GC or vice versa on machines with direct cable entry into an enclosure. Changes in the physical cable size (outside diameter) require cable entry modification and a field change application and report. Cables that are the same size electrically may not have the same outside diameters due to insulation differences.

SMITH Mine Inspector (Electrical) SUBJECT: Field Modification Inspection Report A&CC Par No. 82356 The modifications have been examined and compared to the described changes on the application. The following discrepancies were found: 1) The connection box listed on the Description of Components Added sheet and the Packing Gland and Cable Data Sheet No. 1 of 2 was identified as serial number 37148L, but the manufacturer's plate listed it as 3714BL. The manufacturer was contacted and the serial number 3714BL is correct. 2) The fuses providing protection for the headlight circuit were specified as 10 amperes, but one of the fuses installed was rated at 20 amperes. It was replaced with a properly rated fuse. All discrepancies were corrected and the modifications were judged not to increase the fire and explosive hazards involved in the operation of this machine in gassy or dusty mines.
