RULE 342 - CONTROL OF OXIDES OF NITROGEN (NOx) FROM BOILERS, STEAM GENERATORS AND PROCESS HEATERS
(Adopted 3/10/1992, revised 04/17/1997)

A. Applicability

This rule applies to boilers, steam generators, and process heaters with rated heat inputs greater than or equal to 5 million Btu per hour used in all industrial, institutional, and commercial operations.

B. Exemptions

C. Definitions

D. Requirements - Emission Standards

E. Requirements - Equipment

F. Requirements - Compliance Determination

G. Requirements - Testing

H. Test Methods

Compliance with the NOx emission requirements and the stack-gas carbon monoxide and oxygen requirements of section D shall be determined using the following test methods.

I. Recordkeeping

J. Reporting Requirements

The owners and operators of units subject to Sections D1, D.2.a, D.2.b, and D.2.d shall submit compliance test reports on each unit for each fuel burned. Test reports shall include operational characteristics of all flue-gas NOx reduction equipment or technology.

K. Compliance Schedule

The owner or operator of units subject to this rule shall:

 


ATTACHMENT 1
Equipment Tuning Procedure(1)
Nothing in this Equipment Tuning Procedure shall be construed to require any act or omission that would result in unsafe conditions or would be in violation.of any regulation or requirement established by Factory Mutual, Industrial Risk Insurors, National Fire Prevention Association, the California Department of Industrial Relations (Occupational Safety and Health Division). the Federal Occupational Safety and Health Administration, or other relevant regulations and requirements.

 

Fuel Measurement Value
Gaseous CO Emissions 400 ppm
#1 & #2 smoke-spot number number 1
#4 oil smoke-spot number number 2
#5 oil smoke-spot number number 3
Other oils smoke-spot number number 4
 


1.

1 1. This tuning procedure is based on a tune-up procedure developed by KVB, Inc. for the EPA.

2.

2 2. The smoke-spot number can be determined with ASTM Test Method D-2156 or with the Bacharach method. ASTM Test Method D-2156 is included in a tuneup kit that can be purchased from the Bacharach Company.
