SUPPLEMENTAL

NOTICE OF DATA RESPONSE AND ISSUE WORKSHOP
FOR THE HIGH DESERT POWER PROJECT
APPLICATION FOR CERTIFICATION
(97-AFC-1)

On April 2, 1998, staff issued a notice of a workshop to discuss environmental issues, including air quality (the emission offset plan and best available control technology), hazardous materials, and visual resources. Staff has since learned that the Mojave Desert Air Quality Management District's (District) Determination of Compliance (DOC) will only permit one of the three configurations proposed by the applicant (i.e., the 720 MW three train (3F) combined cycle). However, the District intends to include in the DOC an analysis of the other two configurations. Therefore, staff is supplementing the workshop notice to identify that the workshop will include the discussion of the scope of the District's DOC analysis, and how that change may affect the scope of the Energy Commission staff's analyses of the project.

Staff's proposed agenda for the Workshop is attached on the reverse side of this notice. A workshop summary will be posted on the Energy Commission's Internet page (see below). The time, date and location of the workshop have not changed, and will be held:

Tuesday, April 14, 1998
9:30 a.m. - 3 p.m.
Mojave Desert AQMD
15428 Civic Drive
Board Chambers, Second Floor
Victorville, California


The location of the meeting is wheelchair accessible. If you require special accommodations, contact Robert Sifuentes, at (916) 654-5004, five days prior to the workshop. Persons wanting information on how to participate in the Energy Commission's review of the project should contact Ms. Roberta Mendonca, the Energy Commission's Public Adviser, at (916) 654-4489, or toll free in California at (800) 822-6228. Technical or project schedule questions should be directed to Richard K. Buell, Siting Project Manager, at (916) 653-1614, or E-mail at RBuell@energy.state.ca.us. The status of the project and other relevant documents are available on the Energy Commission's Internet page at www.energy.ca.gov/sitingcases/highdesert. News media inquiries should be directed to Assistant Executive Director, Claudia Chandler, at (916) 654-4989.

DATE: April 7, 1998

AGENDA

HIGH DESERT POWER PROJECT
(97-AFC-1)
April 14, 1998 Workshop
9:30 a.m. to 3 p.m.

Introductions -- 9:30 a.m.

Analysis of Alternative Project Configurations -- 9:45 a.m.

• What is the scope of analysis the Mojave Desert Air Quality Management District (District) plans to include in the Determination of Compliance (DOC) for the two alternative configurations? How would this analysis be used to approve an amendment to permit one of the alternative configurations?

• Staff believes that the Energy Commission could only certify the one configuration permitted in the District's DOC. What options do the parties believe exist to address this situation, and what are the advantages and disadvantages of these options?

Air Quality -- 10:30 a.m.

• Emission Offset Plan
  
  • What Information does the District need to issue its Preliminary DOC?
    
  • What Information does the staff need to conduct its Preliminary Staff Assessment (PSA)?
    
  • When can the applicant provide this information?
    
  • Does the project schedule need to be adjusted?

• Best Available Control Technology (BACT)
  
  • What is the status of South Coast AQMD, Air Resources Board and U.S. Environmental Protection Agency BACT analyses?
    
  • High temperature selective catalytic reduction (SCR) technology

• What model turbine(s) will be addressed in the Preliminary DOC?

• Staff's preliminary analysis shows that start up nitrogen oxide (NOx) emissions may contribute to a violation of the nitrogen dioxide (NO2) ambient air quality standards. Discuss mitigation measures that could address this impact.

  
  

Lunch -- 12 p.m.

Hazardous Materials Handling -- 1:30 p.m.

• Discuss revised modeling results of aqueous ammonia accidental release
  
• Discuss mitigation measures
  
• Discuss Federal Risk Management Program level

Visual Resources -- 2 p.m.

• Discus potentially significant visual impacts from the transmission line to the residents of Oro Grande, golfers using the Golf Course, and travelers using El Evado Road
  
• Discuss alternative transmission line routes to mitigate potentially significant visual impacts

Closing remarks -- 2:30 p.m.
