or the Hearing Board, for any article, machine, equipment or contrivance, the use 

of which may cause, eliminate, reduce, or control the issuance of air 

contaminants, which has been constructed or installed without authorization as 

required by Section 301 of this rule, until: 

a. The information necessary to enable the Air Pollution Control Officer to 

make the determination required by Section 303 of this rule, Rule 502, 

NEW SOURCE REVIEW, and Rule 507, FEDERAL OPERATING 

PERMIT PROGRAM, for those sources subject to that rule, is presented 

to the Air Pollution Control Officer; and 

b. Such article, machine, equipment or contrivance, is altered, if necessary, 

and made to conform to the standards set forth in Section 303 of this 

rule, elsewhere in these rules and regulations, and in the California 

Health and Safety Code. 

303.3 In acting upon a Permit to Operate, if the Air Pollution Control Officer finds that 

the article, machine, equipment, or other contrivance, the use of which may 

cause the issuance of air contaminants or the use of which may eliminate or 

December 9, 2004 

Placer County APCD 501 - 9 Rules and Regulations 
reduce or control the issuance of air contaminants, has not been constructed in 

accordance with the Authority to Construct, he or she shall deny the Permit to 

Operate. The Air Pollution Control Officer shall not accept any further application 

for a Permit to Operate the article, machine, equipment, or other contrivance so 

constructed until he or she finds that the article, machine, equipment or other 

contrivance has been reconstructed in accordance with the Authority to 

Construct. 

303.4 The Air Pollution Control Officer shall require enforceable emission limitations as 

permit conditions in authorities to construct and Permits to Operate to assure the 

permanence of surplus actual emissions reductions applied for use as internal 

reductions or emission reduction credits in accordance with Rule 502, NEW 

SOURCE REVIEW; Rule 504, EMISSION REDUCTION CREDITS; and Rule 

507, FEDERAL OPERATING PERMIT PROGRAM. 

303.5 The Air Pollution Control Officer shall determine that an applicant for a permit to 

construct or modify a potential source of air contaminants located within 1,000 

feet from the outer boundary of a school has complied with the applicable 

requirements of California Health and Safety Code Section 42301.6, preparation 

and distribution of a public notice, prior to approving an application for an 

Authority to Construct permit. 

303.6 Approval to construct shall not relieve any owner or operator of the responsibility 

to comply fully with applicable requirements, including applicable provisions of 

the California State Implementation Plan, District Rules and Regulations, or State 

or Federal law. 

303.7 No Permit to Operate shall be issued, modified, or renewed for stationary 

sources that are subject to Rule 507, FEDERAL OPERATING PERMIT 

PROGRAM, unless the permit contains conditions consistent with those specified 

in that rule. 

304 PROVISION OF SAMPLING AND TESTING FACILITIES: In addition to the monitoring 

and testing required to comply with state or federal laws or regulations, the Air Pollution 

Control Officer may, upon reasonable written notice or before an Authority to Construct or 

Permit to Operate is granted, require the applicant or the owner or operator of any article, 

machine, equipment, or other contrivance, the use of which may cause the issuance of 

air contaminants, or the use of which may eliminate, reduce, or control the issuance of air 

contaminants to: 

304.1 Provide and maintain such facilities as are necessary for sampling and testing 

purposes in order to secure information that will disclose the nature, extent, 

quantity or degree of air contaminants discharged into the atmosphere from the 

equipment in question. In the event of such a requirement, the Air Pollution 

Control Officer shall notify the applicant in writing of the required size, number 

and location of sampling holes; the size and location of the sampling platform; 

the access to the sampling platform; and the utilities for operating the sampling, 

testing, and air monitoring equipment. Such platform and access shall be 

constructed in accordance with the applicable General Industry Safety Orders of 

the State of California. 

304.2 Provide and maintain sampling and monitoring apparatus to measure emissions 

of air contaminants when the Air Pollution Control Officer has determined that 

such apparatus is available and should be installed.

a. Continuous emission monitoring systems as a minimum shall be installed 

when required, and to the performance specifications required, by 

Section 502 of this rule. 

b. A violation of emission standards of these rules, as shown by the 

stack-monitoring system, shall be reported by the owner or operator to 

the Air Pollution Control Officer within 96 hours, or such earlier time as 

may be required by Rule 404, UPSET CONDITIONS, BREAKDOWN 

AND SCHEDULED MAINTENANCE. 

c. In the event of a breakdown of monitoring equipment, the owner or 

operator shall notify the Air Pollution Control Officer within 48 hours and 

shall initiate repairs. The owner or operator shall inform the Air Pollution 

Control Officer of the intent to shutdown any monitoring equipment at 

least 24 hours prior to the event. 

d. Compliance with Subsection (b) and (c), above, does not exempt the 

owner or operator from applicable provisions of Rule 404, UPSET 

CONDITIONS, BREAKDOWN AND SCHEDULED MAINTENANCE, the 

emergency provisions of Rule 507, OPERATING PERMIT PROGRAM, 

pursuant to 40 CFR 70.6(g), or the separate reporting requirements of 

other federal regulations to which the stationary source or emissions unit 

is subject. 

304.3 If the Air Pollution Control Officer determines that technological or economic 

limitations on the application of measurement methodology to a particular class 

of sources would make the imposition of a numerical emission standard 

infeasible, the Air Pollution Control Officer may instead prescribe a design, 

operational, or equipment standard. In such cases, the Air Pollution Control 

Officer may require the installation or modification of process monitoring devices 

such that the design characteristics or equipment will be properly maintained, or 

that the operational conditions will be properly performed, so as to continuously 

achieve the assumed degree of control. To the extent applicable, reporting 

requirements for process monitors shall be the same as for continuous emission 

monitoring systems. 

304.4 A person operating or using a stack monitoring system shall, upon written notice 

from the Air Pollution Control Officer, provide a summary of the data obtained 

from such systems. This summary of the data shall be in the form and manner 

prescribed by the Air Pollution Control Officer. The summary of data shall be 

available for public inspection at the office of the Air Pollution Control District. 

Records from the monitoring equipment shall be kept by the owner or operator 

for a period of two (2) years, during which time they shall be available to the Air 

Pollution Control Officer in such form as he or she directs. 

 304.5 The responsible official of a source using a stack monitoring system and subject 

to Rule 507, FEDERAL OPERATING PERMIT PROGRAM, shall in addition to 

the requirements of Section 304.4, above, submit data summaries and retain 

monitoring records in accordance with the applicable federal requirements of that 

rule. 

305 TRANSFER: An Authority to Construct or Permit to Operate shall not be transferable, 

whether by operation of law or otherwise, either from one location to another, from one 

piece of equipment to another, or from one person to another. In the event any person 

contemplates or desires to make any such transfer as herein above described, said 

December 9, 2004 

Placer County APCD 501 - 11 Rules and Regulations 
person shall make an application for authorization in accordance with Section 403 of this 

rule. 

306 PERMIT RENEWAL: Except for Title V permits, which shall be renewed in accordance 

with Rule 507, FEDERAL OPERATING PERMIT PROGRAM, every Permit to Operate, 

except as specified below, shall be renewable annually on the permit's anniversary date, 

commencing one (1) year after the date of issuance. 

306.1 Action to suspend or revoke the permit has been initiated and such action has 

resulted in a final determination to suspend or revoke the permit by the Air 

Pollution Control Officer or the Hearing Board and all appeals, or time for 

appeals, has been exhausted.
