Cedar Springs, Georgia 31732
Dear Ms. Clark:
This responds to your letter of October 8, 1999, requesting clarification of the attendance requirements for unloading tank cars under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if the interpretation concerning attendance requirements for tank car unloading published in the Federal Register on February 28, 1990, remains in effect.
The answer is yes. Electronic monitoring of tank car unloading to comply with the attendance requirements in § 174.67(I) of the HMR is permitted provided the conditions listed in your letter are met. You need not have an exemption to utilize electronic sensors to monitor tank car unloading operations.
I hope this information is helpful. If you have further questions, please do not hesitate to contact this office.
