The purpose of this rule is to limit emissions of volatile organic compounds (VOC) 

from operations involving the management of biosolids, animal manure, or poultry 

litter. 

2.0 Applicability 

The provisions of this rule apply to all facilities whose throughput consists entirely or 

in part of biosolids, animal manure, or poultry litter and the operator who landfills, 

land applies, composts, or co-composts these materials. 

3.0 Definitions 

3.1 Active Composting: the phase of the composting process that begins when 

organic materials are mixed together for composting and lasts until one of the 

following conditions is met: 

3.1.1 The organic material emits no more than seven (7) mg carbon dioxide 

per gram of organic material (CO2-C) per day, as measured using the test 

method in Section 6.2.1.1; or 

3.1.2 The material has a Solvita Maturity Index of 5 or greater as measured 

using the test method in Section 6.2.1.2; or 

 3.1.3 The material has been composted for a period of at least 22 consecutive 

calendar days. 

3.2 Aerated Static Pile: a system designed, constructed, maintained, and operated 

for decomposing organic material in which the material is placed on top of 

perforated plates or pipes that are connected to blowers that either push or pull 

air through the piles. 

3.3 Alternative Mitigation Measure: a mitigation measure, proposed by the 

operator, that is determined by the APCO and EPA to achieve VOC reductions 

that are equal to or greater than the VOC reductions that would be achieved by 

other mitigation measures listed in this rule, that operators could choose as a 

means of complying with rule requirements. 

3.4 Animal Manure: non-human animal excretions and waste, including, but not 

limited to, dried solids and urine from cows, cattle, or swine.

source test data obtained in accordance with Section 6.2 of this rule and 

the material and mixtures of materials is representative of normal 

operations. 

6.3.4 The APCO and EPA shall provide interim approval of the compliance 

plan provided the operator submits all of the information required under 

Section 6.3.1 and the APCO and EPA verifies that, by design, the 

compliance plan will reduce emissions similar to or greater than listed 

mitigation measures. 

6.3.5 Following the interim approval of the compliance plan, the APCO and 

EPA shall approve the compliance plan provided the operator submits, 

no later than 180 days after the effective date of compliance, a 

certification of the compliance report that includes all source test data, 

and the APCO and EPA verifies that the emissions from the mitigation 

measure meets the emission reduction limits. 

6.3.6 The APCO and EPA may impose conditions necessary to ensure that the 

operation complies with the compliance plan and all applicable District 

rules.

consistent with the compliance plan necessary to demonstrate compliance 

with the compliance plan. 

6.3.8 Compliance with the provision of the approved proposal does not exempt 

an operator from complying with the requirements of the California 

Health and Safety Code or any other District rule.

 (Wcurrent) 
SJVUAPCD 4565 - 20 3/15/2007

Where 

% converted = the estimated percent of current compost/cocompost operations that would be converted to 

energy generation operations (%) 

Wenergy = the estimated throughput of biosolids, animal manure 

or poultry litter and other materials used in energy 

generation operations (wet tons/year)

calendar years 2002 through 2006 (wet tons/year) 

7.4.1.2 All data, calculations methodology, calculations, records, 

manufacturer specifications, and all other information necessary

matter and ozone formation, after accounting for any increases 

in oxides of nitrogen (NOx) emissions from the project. 

7.4.2 If the percent converted to energy generation operations in Section 

7.4.1.1 is less than 100%, the unconverted composting/co-composting 

operations shall be in compliance with all provisions of the rule by the 

compliance schedule in Section 7.3.1 or Section 7.3.2, as appropriate; 

and 
SJVUAPCD 4565 - 21 3/15/2007

7.4.3 On and after September 15, 2008, the operator shall implement four (4) 

Class One mitigation measures from Table 2 for all compost/co-compost 

operations that would be converted to energy generation operations. 

These mitigation measures shall remain in place until 7.4.4 is 

implemented or the compost/co-compost operations are converted to 

energy generation operations, whichever comes first; and 

7.4.4 On and after September 15, 2012, the operator shall implement three 

Class One mitigation measures and operated in-vessel composting 

systems, for both the active and curing phases of composting of all 

composting/co-composting operations, at the facility, that were
