On February 23, 2005, the U.S.
Department of Transportation, Pipeline and Hazardous Materials Safety
Administration, Office of Pipeline Safety (OPS) issued a final rule
adopting as a final rule, the interim final rule which was issued on
January 5, 1993. This final
rule also made minor amendments to some of the regulations in Part 194
in response to public comments and the experience that OPS gained in
implementing the interim final rule, leading spill response exercises,
and responding to actual spills. The amendments were generally
technical in nature and did not involve additional costs to pipeline
operators or the public.
In issuing the final
rule, a table was inadvertently misprinted. This table in
§194.105(b)(3) specifies the potential spill volume reduction
credits operators may use when they have secondary containment and
other spill prevention measures on breakout tanks. These spill
reduction credits are used when calculating the worst case discharge
volume. The correct table is given below:
(b) * * *
(4) Operators may
claim prevention credits for breakout tank secondary containment and
other specific spill prevention measures as follows:
Prevention measure | Standard | Credit (percent) |
Secondary containment > 100% | NFPA 30 | 50 |
Built/repaired to API standards | API STD 620/650/653 | 10 |
Overfill protection standards | API RP 2350 | 5 |
Testing/cathodic protection | API STD 650/651/653 | 5 |
Tertiary containment/drainage/treatment | NFPA 30 | 5 |
Maximum allowable credit | 75 |
