Recent Power Plant News & Events

• San Juan Generating Station is in the process of a 4-yr $320 million environmental upgrade– 2 units complete, remaining 2 units complete by Spring 2009 – Substantial reductions in NOx, SO2, and Mercury (Hg) – Approx. NOx 35%, Hg 85%+– Environmental Upgrade resulting from consent decree

amongst PNM, NMED, Sierra Club, and Grand Canyon Trust– Preliminary Projections:

• 11,000 tons per year SO2 reduction• 9,000 tons per year NOX reduction• Decrease in opacity excursions• 800 lbs Hg per year reduction

• DREF air permit issued– However, state and environmental groups suing on multiple

grounds including CO2– Construction is delayed pending law suits

Four Corners Agency Actions on Power Generation

• Consent decree oversight• EPA Regions 6, 8 & 9 and AZ, CO, NM and UT are

evaluating a range of options for NOx controls (including SCR) for BART under the Regional Haze Rule.

• NM Tax credits available for IGCC and CCS• GHG inventory moving forward and other rules

being developed• NM has spent considerable time commenting &

making environmental mitigating suggestions conc. the DESERT ROCK ENERGY PROJECT and at this time is opposing the project legally on certain grounds.

Oil & Gas Wells in Four Corners (as of 2003)

OIL and GAS PRODUCTION• The Farmington BLM RMP & EIS states that “the NM portion of

the San Juan Basin supports approximately 18,000 active oil and gas wells and there are more than 2,400 existing oil and gas leases in the planning area

• 10,000 new wells were estimated to be drilled in NM on Federal land portion of San Juan Basin as part of the 20 yr BLM reasonable foreseeable development RMP (2001) and evaluated in the Farmington Resource Management Plan & EIS Record of Decision (2003)

• The scope of the BLM RMP is approximately 1,415,300 acres of public land and 3,020,693 acres of federal minerals in San Juan, McKinley, Rio Arriba and Sandoval Counties. The overall planning area encompasses 8,274,100 acres.

• There are addition existing gas wells and projected growth in the Northern San Juan Basin in Colorado, and outside the BLM jurisdiction in NM portion of San Juan Basin.

• Many small unregulated sources• Multiple Operators• Changing Field Conditions

VOC, SO2, CO, PM, NOx

Four Corners Air Quality Task Force

• Began meeting November 2005• Approximately 250 members and

interested parties• Task Force Report final version

released November 2007– Report includes mitigation options

developed by task force members– Over 500 pages

• http://www.4cornersair.org

Four Corners Agency Action on Oil & Gas Production

• Federal Land Managers (BLM, FS, NPS), EPA and Tribes working cooperatively to minimize impacts– BMPs for Tanks– Optimization, Centralization, Co-location– Control of existing/new engines in

permits to drill

• EPA working on rule/protocol for using Optical imaging for leak detection

NM Action on Oil & Gas Production• Existing Engines: NM is evaluating the need for new regulations.

Has worked with BLM to incorporate a limit in the Permit to Drill COA

• New Engines: EPA New Source Performance Standard (NSPS) Subpart JJJJ Summary– Effective March 18, 2008– Applies to new, modified and reconstructed stationary spark ignition

(SI) internal combustion engines (ICE), regardless of size and combusting any fuel

– Emissions controlled to levels achievable by Best Demonstrated Technology (BDT)

– regulated pollutants: NOx, CO and VOC, plus sulfur limit on gasoline– Phased in from manufacture dates from 2007 to 2011 and beyond)– NMED has prepared a white paper summary on the new rule and is

currently in process of conducting industry outreach on the new rule in San Juan County

• NM also has San Juan VISTAS program with 3 partners who have pledged to voluntarily reduce some emissions leading to ozone, haze, & climate change

• Continued inventory and modeling work with goal of maintaining and/or improving air quality

Four Corners Agency Action on Other Sources

• adopt tougher emissions standards for new vehicles in New Mexico. The standards will apply to new vehicles sold in New Mexico _ not used cars or new cars before the 2011 model year. (Being challenged in court)

• NM is in the development process of a fugitive dust regulation

• Statewide Open burning rule in effect (enforcement of trash burning)

• NM will soon commence a school bus retrofit project in San Juan County with federal funding

Four Corners Agency Action on Renewable Energy, Energy Efficiency, & Conservation

• CO & NM have implemented a range of Energy Efficiency measures and incentives for renewable energy and conservation.

• Measures have been included in Supplemental Environmental Projects• There is an RFP out from utilities El Paso Electric, Xcel Energy, PNM, and Tri-

State Generation and Transmission Association seeking detailed proposals from solar developers for the construction of a solar parabolic trough generation facility to provide solar electricity to each of the utilities by 2012. Scale in the range of 100 MW

• The Federal gov’t just now in Oct 2008 extended federal solar tax credit for 8 more years which now includes commercial entities & utilities– An 8-year extension of the residential and business Investment Tax Credit (ITC) for

solar, small-wind and geothermal systems – An elimination of the US $2,000 cap on the residential ITC – Elimination of the prohibition on utilities from obtaining the ITC – Authorization of US $800 million for clean energy bonds for renewable energy

generating facilities – A 1-year extension of the PTC for wind projects – A 2-year extension of the PTC for geothermal facilities – Creates a 2 year ITC for marine energy technologies (tidal, wave, current, ocean

• The 3-year average design values for the 3 San Juan County ozone monitors in 2008 are currently 0.065, 0.071, and 0.077 ppm.

• Recent preliminary monitoring data shows that due to the strengthened ozone standard and some high ozone days at Navajo Lake monitor in October, we have reached the threshold for attainment status and exceeded it at Navajo Lake site. A three yr avg of annual 4th highest 8-hour avg ozone at Navajo site is now 0.077 ppm compared to the new standard of 0.075 ppm. A timeline showing dates for recommending non-attainment and designation follows this slide.

• Both other monitors in San Juan County (Bloomfield and Substation) have never exceeded the ozone standard.

• We have exceptional monitoring staff in San Juan County

• There are other monitors just North of NM border that we use to assess regional air quality and we have done passive ozone studies and other research throughout the area

New NAAQS 8-hour Ozone Standard (0.075 PPM March 2008)

If area goes non-attainment

• Nonattainment Areas Areas formally declared in violation of the NAAQS and areas contributing to a violation are designated “nonattainment areas.” Nonattainment areas must meet certain Clean Air Act requirements, such as:

– Transportation Conformity - Requires a demonstration that regional long-range transportation plans will not negatively impact air quality, or federal transportation funds can be withheld

– New Source Review - Requires a review of new or modified industrial operations to minimize air pollution.

– Rate of Progress Requirements - A certain percentage of pollutants must be reduced each year.

– Specific attainment date - Consequences of failure to reach attainment by the specified date include stricter control measures and the potential for stiff penalties.

– 10-year maintenance plan - Includes additional or continuing mandatory programs for 10 years following redesignation to attainment.

• Another requirement obligates the state to develop and implement a prescriptive, enforceable clean air plan that mandates how the area will come into compliance with the NAAQS that is exceeded. The enforceable clean air plan and revisions to it are known as the State Implementation Plan (SIP).

Other Industry Actions

• Some other companies have environmental stewardship programs @ our last Task Force meeting we had 5 companies present including– 2 Vistas Partners: Conoco & Red River– BP – VOC reductions w/well completion process– Red Willow – lean burn compressors / adding catalysts to meet

2011 NSPS requirements– & San Juan Generating Station

• San Juan Generating Station is currently in process of environmental upgrade w/significant emissions reductions– Now projecting approximately

• 11,000 tons per year SO2 reduction• 9,000 tons per year NOX reduction• Decrease in opacity excursions• 800 lbs Hg per year reduction

• Some other Four Corners O&G companies participate in GAS STAR program which can have indirect reductions of ozone precursors

“It really is up to all of us to work together to protect our air quality in New Mexico. The key is that everyone needs to participate and no one should hesitate to take action, no matter how small or inconsequential that action may seem.”
