INTRODUCTION

Operating Permit Number P062R1M1 is issued by the Air Quality Bureau of the New Mexico 

Environment Department ("Department") to Public Service Company of New Mexico (“permittee”) 
Operating Permit No. P062R1M1 Page 2 of 42 

pursuant to the federal Clean Air Act ("federal Act"), the New Mexico Air Quality Control Act 

("state Act") and regulations adopted pursuant to the state and federal Acts, including Title 20, New 

Mexico Administrative Code, Chapter 2, Part 70 (20.2.70 NMAC) - Operating Permits. This permit 

authorizes the operation of this facility located at UTM Zone 12, UTMH 728.5 km, UTMV 4075.6 

km, approximately 3 miles north-northeast of Waterflow, New Mexico in San Juan County. 

This facility consists of four coal-fired electric generating units and associated support facilities. 

Each coal-fired unit burns pulverized coal and No. 2 Diesel oil in a boiler and produces highpressure steam which powers a steam turbine coupled with an electrical generator. Electrical power 

produced by the units is supplied to the electric power grid for sale. Coal for the units is supplied by 

the adjacent San Juan Mine and is delivered to the facility by conveyor. For the purposes of this 

permit, the four generating units at San Juan Generating Station are designated Unit 1, Unit 2, Unit 

3, and Unit 4. 

This modification consists of raising the carbon monoxide (CO) emissions limits for Boiler Units 

1-4 to reflect the results of recent stack testing as allowed by NSR Permit 0063M3. 

This permit P062R1M1 supersedes permit P062R1, and will expire February 04, 2010, pursuant to 

20.2.70.302.B NMAC. Application for renewal of this permit is due twelve (12) months prior to the 

date of expiration, pursuant to 20.2.70.300.B.2 NMAC.

Pursuant to 20.2.70.302.A.1 NMAC, the Department specifies with this permit, terms and conditions 

upon the operation of this facility to assure compliance with all applicable requirements, as defined 

in 20.2.70 NMAC at the time this permit is issued or as specified in the schedule of compliance 

contained herein. 

Pursuant to the New Mexico Air Quality Control Act NMSA 1978, Chapter 74, Article 2, all terms 

and conditions in this permit, including any provisions designed to limit this facility's potential to 

emit, are enforceable by the Department. Pursuant to 20.2.70.302.A.5 NMAC, all terms and 

conditions are enforceable by the Administrator of the United States Environmental Protection 

Agency ("EPA") and citizens under the federal Act, unless the term or condition is specifically 

designated in this permit as not being enforceable under the federal Act. 

PERMIT SHIELD
