Epa regulatory update

EPA Regulatory Update

Jodi Howard at EPA OAQPS conveyed the latest to me:

  • On Jan 15, 2008, ACC/API/NPRA submitted a petition for reconsideration of NSPS VV, VVa, GGG, and GGGa rules. Then EPA issued a stay effective Aug 1, 2008. http://edocket.access.gpo.gov/2008/E8-11400.htm

    • Revision was to be published on May 15, 2011.

    • Will add annual M21 monitoring requirement and address the definitions of process unit, connector monitoring requirements in VVa, shared storage tank allocations to specific units, and capital expenditure (presently advised to use provisions of VV).


Epa regulatory update1

EPA Regulatory Update

Alternative Work Practice (AWP)

  • Finalized Dec 22, 2008, covers Parts 60, 61, 63, 65,and RCRA CC.

  • EPA petitioned for reconsideration Feb 20, 2009.

  • Goal to publish revisions summer 2011.


Epa regulatory update2

EPA Regulatory Update

What lessons can be learned from the AWP?

  • Most equipment doesn’t leak

  • 84% of the emissions come from 0.13% of components (1997 API publ. 310, “Analysis of Refinery Screening Data”, Tabacket al.)

  • Calibrations are painful

  • Non-traditional components can be more easily surveyed

  • Silver bullet?

  • Let me give you a visual, courtesy of an EPA presentation from way back in Oct 2002…

    Epa regulatory update3

    EPA Regulatory Update

    On Mar 30, 2011, EPA published an interim rule effective immediately requiring most industrial facilities to include fugitive emissions when determining the applicability of the NSR program.

    • The interim rule extends the stay of the “Fugitive Emissions Rule” from Dec 19, 2008, and reversed EPA's policy that fugitive emissions must be included in determining whether a physical or operational change triggers NSR requirements.  The rule limited the sources that must include fugitive emissions in an NSR determination to major sources at the 100 tpy threshold (e.g., fossil-fuel boilers > 250 BTU/hr and stationary source categories regulated under §§ 111 or 112 as of Aug 7, 1980).

    • EPA notes that the Mar 30, 2011 interim rule revises, reinstates, and stays portions of 40 CFR Parts 51 and 52, which were amended by the 2008 Fugitive Emissions Rule, to clarify the "potential" confusion that arose following a previous stay issued in Mar 2010.


    Epa regulatory update4

    EPA Regulatory Update

    Equipment Leaks Uniform Standard

    • Destined for Part 65 as a technology review, included in EPA’s Chemical Sector Initiative.

    • “One stop shop” for Parts 60, 61, and 63.

    • Goal to publish Jul 7, 2011.


    Consent decrees

    Consent Decrees

    • Consent Decree defined: A settlement of a lawsuit or criminal case in which a person or company agrees to take specific actions without admitting fault or guilt for the situation that led to the lawsuit.

    LDAR CD Basics

    • LDAR Program Description

    • LDAR Training

    • Identification of LDAR Coordinator and Duties

    • LDAR Auditing

    • Corrective Actions, for ANY Non-Compliance

    • Lower leak definitions, more frequent monitoring and reporting, implementing new tools/equipment (a.k.a., “SMART” LDAR)

    • QA/QC requirements

    • Delay of Repair

    • Chronic Leakers

    • Recordkeeping and Reporting Requirements

    • Benzene NESHAP

    Consent Decree Update

    Refining:EPA continues negotiations with 6 refiners (for an additional ~5% of domestic refining capacity)

    http://www.epa.gov/compliance/resources/cases/civil/caa/refineryinitiative-powerpoint021111.pdf

    • Emissions reductions as of Feb 11, 2011:

      • NOx by more than 92,000 tons per year

      • SO2 by more than 255,000 tons per year

      • Air Toxics: Benzene and other VOCs (unquantifiable fugitive emissions)

    • Injunctive Relief: Over $6 billion in control technologies

    • Civil Penalties: Over $80 million

    • Supplemental Environmental Projects: $75 million

    Chemical plants: EPA appears to be slower in issuing CD’s for those of us in petrochem.

    • Many of the existing ones are used by both EPA and industry for negotiations of CD provisions and ‘stips’.

    • Finding these Consent Decrees on the web isn’t easy.


    Ldar cd update

    LDAR CD Update

      • Installation of "low-leaking" valve or valve packing technology


    Ldar cd s newer concepts

    LDAR CD’s, Newer Concepts

    Leak Trend Analysis– An analysis of 5 years of data to determine whether one or more of the following issues result in a trend in leaks or “no leaks”:

    • Service type (light liquid, gas, etc.);

    • Service and operating characteristics of the stream (temperature, pressure, line diameter, corrosivity, vibrational movement, etc.);

    • Material compatibility;

    • Equipment type, design, materials of construction, and manufacturer;

    • For valves, the valve packing type;

    • The Screening Values observed in each monitoring event before repair, the repair methods used, and the Screening Values after repair;

    • Average time to failure based on equipment type and manufacturer, packing type, seal type, or other equipment attributes relating to the generation of leaks.


    Ldar cd s newer concepts1

    LDAR CD’s, Newer Concepts

    Preventative Maintenance and Replacement Action Plan (PMRAP)– After completing a Leak Trend Analysis identifying at least one trend, develop a PMRAP:

    • Results of the Leak Trend Analysis;

    • Description of Each Action, and a Schedule, to Eliminate or Minimize the Effects of the Factors and Conditions that Result in Leak Trends and/or Weaker Performance;

    • Replacement of Weaker-Performing Pieces of Equipment with Better-Performing ones;

    • Equipment Purchases. To the extent that new or replacement equipment is installed, ensure that better performing equipment, if available, is installed and document any reasons why better performing equipment was not installed.
