Emissions regulations nsps and regional regulations

Emissions Regulations – NSPS and regional regulations

  • National

    • EPA defines minimum standards and rules for the U.S.

      • New Source Performance Standards, Nonroad Source Rules

      • National Air Quality Attainment Requirements

  • States or Local

    • State Specific Standards (at least as strict as EPA)

      • Permits

    • Critical Area Rules: Non-attainment, Parks, BLM etc.


National si nsps and neshap

National - SI NSPS and NESHAP

  • SI NSPS : (Stationary) Spark Ignited New Source Performance Standards

    • Published January ’08, Effective March ’08.

    • 1st New engine requirements retroactive to July ‘07.

    • 1st Remanufactured or Modified (RM) engine requirements retroactive to June ’06.

    • Applies to new, reconstructed or modified stationary engines.

    • Based on the date of engine manufacture, reconstruction or modification, not the date of installation.


National si nsps emissions standards

National - SI NSPS Emissions Standards

  • There are alternate ppm values that may be advantageous depending on engine efficiency.

  • There are standards for other applications as well. (ie. Landfill, etc.)


National neshap and si nsps

National - NESHAP and SI NSPS

  • NESHAP : National Emissions Standards for Hazardous Air Pollutants

    • Update to existing rule published January ’08, Effective March ’08.

    • Existing requirements back to ’02.

    • Applies to new or reconstructed stationary engines.

      • Are working on applying rule to all existing stationary engines.

    • Newly regulated engines only have to meet SI NSPS.


Neshap n otice of p roposed r ule m aking

NESHAP Notice of Proposed Rule Making

  • National Emission Standards for Hazardous Air Pollutants for Reciprocating Internal Combustion Engines; Proposed Rule change.

    • Would change 40 CFR 63, subpart ZZZZ

  • Regulates all previously unregulated SI and CI existing and new stationary engines.

    • Intended to drive the use of Catalysts

    • Adds Startup, Shutdown and Malfunction Requirements

    • Adds Mandatory Maintenance Requirements

  • Over 180 comments were submitted.


Neshap n otice of p roposed r ule m aking1

NESHAP Notice of Proposed Rule Making


Neshap n otice of p roposed r ule m aking2

NESHAP Notice of Proposed Rule Making

  • HAPs - ~188 regulated compounds

    • Represented by a surrogate: Typically Formaldehyde, CO or VOC

  • Major Source – @ site, 10 tons/yr single HAP, or 25 tons/yr all HAPs

  • Area Source – Anything that is not a Major Source

NESHAP Notice of Proposed Rule Making


Example of proposed neshap ruling

Example of Proposed NESHAP Ruling

  • G3406 NA Engine purchased in 1996

  • 215 bhp at 1800 rpm Rich Burn

  • Area Source Compression site anywhere in the USA

  • Requires change from Standard “Best Efficiency” to Catalytic setting

  • Normal operation

    • 40CFR60 JJJJ

    • 40CFR63.6590c

  • Startup, Shutdown & Malfunction


State emissions highlights

State Emissions Highlights

  • Colorado, East Slope (Denver Area) Nonattainment

  • Wyoming, Sublette County

  • New Mexico, Aftertreatment Permits

  • Texas, HGB Nonattainment

  • Regional Regulation Activity


Colorado east slope denver area non attainment area

Colorado, East Slope (Denver Area) Non-attainment Area

  • The Denver area did not meet the federal 8 hour Ozone requirements

    • Colorado submitted a State Implementation Plan (SIP) that shows compliance by 2012


Colorado east slope denver area non attainment area1

Colorado, East Slope (Denver Area) Non-attainment Area

  • New Rule

    • New, modified or relocated-into-the-state SI ICE must meet the SI NSPS emissions standards in place when the installation occurs.

    • Existing RB ICE >500 hp must have 3 way catalysts, and Air/Fuel controllers by May 1, 2010.

    • Existing LB ICE >500 hp must have oxidation catalysts by May 1, 2010, unless they are built before June 1, 2004 and the retrofit costs more than $5000/ton VOC.

    • Engines regulated under 40 CFR 60, or operating under MACT or BACT requirements are excluded.


New mexico

New Mexico

New Mexico

  • Changes “Notice of Intent” Permit Policy

    • Previously did not count aftertreatment in their consideration of “potential emission rate”.

    • Aftertreatment used in meeting the CI NSPS, SI NSPS or NESHAP will now be accepted.

    • Limits the number of engines that need to go through the full air permit process.


Wyoming

Wyoming

  • Interim Permit Policy in Sublette County

    • 1 Measurement > Ambient NOx standard

    • Effectively caps VOC and NOx Emissions

    • Requires reduction of 1.5:1 for VOC, and 1.1:1 for NOx

  • Still Working on Permanent Measures

    • Gas engines to replace diesel engines in drill rigs

    • SCR in diesel drilling application

    • Regulation of Diesel Engines as Stationary


Texas hgb nonattainment

Texas, HGB Nonattainment

  • The Houston Area has been redesignated as a Severe Nonattainment area.

    • SIP update by 4/15/10.

    • Mandatory CAA compliance by 6/15/19

    • New rules for engines in the area likely.

HGB – Houston-Galveston-Brazoria


Regional regulation activity

  • Four Corners Task Force

    • National engine emission rules will improve air quality without other measures.

    • Adding 3-way catalysts to existing RB engines is the only engine measure that showed other significant improvement.

  • Marcellus Shale

    • Just now evaluating potential air quality impacts.

    • Initial focus is on limiting drilling emissions.

  • Oklahoma & Arkansas

    • SI NSPS is enough for now.

Regional Regulation Activity


Key summary points emission regulations review of nsps regional regulations

Key Summary Points Emission Regulations – Review of NSPS & regional regulations

  • National Regulations

    • NSPS

      • Applies to every new engine

      • Based on born on date

      • Next key date is July 1st, 2010

    • NESHAP

      • Proposed plan has not been finalized

      • Based on start up date

      • Next key date is February 10th, 2010

  • States or Local

    • Typically more strict than National Regulations

    • Non – Attainment Areas
