Monitoring Bypassed Safety Devices

This Notice to Lessees and Operators (NTL) supersedes NTL No. 2005-G01, effective January 6, 2005, on this subject. In addition to providing clarification and guidance for monitoring bypassed production and pipeline safety devices, this NTL addresses related questions that have arisen since the 2005 NTL was issued. Specifically, this NTL explains the meaning of minimum number of safety devices, provides policy regarding Emergency Support Systems and other support systems, and updates contact information.

In accordance with 30 CFR.250.803(c)(I), you may bypass safety devices for production safety systems only if:

  1. The safety devices are temporarily out of service for startup, maintenance, or testing;
  2. The minimum number of safety devices is out of service at anyone time;
  3. Personnel monitor the bypassed functions until the safety devices are placed back in service; and
  4. The temporarily out-of-service safety devices are flagged so that they may be readily identified.

In accordance with 30 CFR 250.1 004 ( c), you may continue to operate a pipeline when required safety equipment has been rendered ineffective or removed from service only if:

  1. An equivalent degree of safety is provided; and
  2. The safety equipment is identified by a sign placed on the equipment stating that the equipment has been rendered ineffective or removed from service.
