9.0 Equipment Certification Requirements

9.1 To be considered for APCO certification, the ma nufacturer or operator shall comply with the following requirements:

9.1.1 Certification shall be based upon the emissio n source testing results of a specific unit, or a randomly selected unit of each model, or retrofit control technology.

9.1.2 A source testing protocol shall be submitted in acc ordance with the provisions of Rule 1081 (Source Sampling) for appro val by the APCO prior to conducting the source test. The source te sting protocol approved by the APCO shall be strictly adhered to d uring certification source testing.SJVUAPCD 4307 - 16 05/19/11 9.1.3 Source testing shall be conducted over the range of operating parameters for which the unit(s) or retrofit control technolog y will be operated.

9.1.4 The source testing results shall demonstrate compliance with the emission limits of this rule for each model of unit(s), or r etrofit control technology

to be certified.

9.1.5 The source testing procedure and reports shal l be prepared by an ARBapproved independent testing laboratory, and shall contain all the elements identified in the APCO-approved source testing prot ocol.

9.1.6 Source testing shall be conducted no more tha n 90 days prior to the date of submission of request for certification by the APCO

.

9.2 The manufacturer or operator requesting certifi cation shall submit to the APCO the following information:

9.2.1 Copies of the source testing results conducte d pursuant to the requirements of Section 9.1, and other pertinent technical data to demonstrate compliance with the emission limits of this rule.

9.2.2 The applicant shall sign and date the stateme nt attesting to the accuracy of

all information in the statement.

9.2.3 Name and address of the unit manufacturer or operator, brand name of the unit or retrofit control technology, model number, rated heat input as it appears in the unit nameplate, and description of m odel of unit(s), or retrofit control technology being certified.

9.3 The APCO will only approve an application for c ertification to the extent that the requirements of Sections 9.1 through 9.2 are met an d the source testing results

demonstrate that the emission limits of this rule a re met.

9.4 The APCO-approved certification is valid only f or the range of operating parameters for which certification is issued.

9.5 A certified unit or a certified retrofit contro l technology that is operated outside the APCO-certified range of operating parameters sh all lose its certification status. A unit or retrofit control technology that loses it s certification status shall comply with the requirements of Section 6.3.3.

9.6 The APCO shall publish a list of certified unit s or certified retrofit control technology after the certification process is compl eted.
