1.0 Purpose

The purpose of this rule is to limit emi ssions of volatile orga nic compounds (VOC) from Confined Animal Facilities (CAF).

2.0 Applicability

The provisions of this rule shall appl y to any Confined Animal Facility.

3.0 Definitions

3.1 Aerated Static Pile (ASP): a system designed, constructe d, maintained, and operated for decomposing or ganic 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.

3.2 Aerobic Digester: a basin or tank designed, constructe d, maintained, and operated for the aerobic treatment of liqui d or solid manure that is approved by the APCO, ARB, and EPA.

3.3 Aerobic Lagoon: a lagoon designed, c onstructed, maintained , and operated in accordance with the applicable standa rds for aerobic lagoons in the Natural Resource Conservation Service (NRCS) Ca lifornia Field Office Technical Guide Conservation Practice Sta ndard Code 359 or othe r applicable standards approved by the APCO, ARB, and EPA.

3.4 Alternative Mitigation Measure: a mitig ation measure that is determined by the APCO, ARB, and EPA to achieve reductions that are equal to or exceed the reductions that would be ach ieved by other mitigation m easures listed in this rule that owners/operators could choose to comply with rule requirements.

3.5 Anaerobic Digester: a basin or tank designed, constructe d, maintained, and operated for the anaerobic treatment of liquid or solid manure in accordance with the applicable sta ndards for anaerobic digester s in the Natural Resource Conservation Service (NRC S) California Field Of fice Technical Guide Conservation Practice Standard Code 365 or 366 or other app licable standards approved by the APCO, ARB, and EPA.

3.6 Anaerobic Treatment: the decomposition of organic matter by microbes in the absence of oxygen. During th is process four main reac tions occur. In the first reaction, complex organic materials (e.g . carbohydrates, proteins, and fats) are hydrolyzed to form soluble organic mol ecules (e.g. sugars, amino acids, and

SJVAPCD 4570 - 1 10/21/2010fatty acids). In the second reaction, soluble organic mo lecules ferment to form acetic acid, formic acid, and volatile fatty acids. In the third reaction, volatile fatty acids undergo acetogenesi s to form acetic acid a nd formic acid. In the fourth reaction, acetic acid and formic acid undergo methanogenesis to form methane and carbon dioxide.

3.7 Anaerobic Treatment Lagoon: a lagoon designed, constr ucted, maintained, and operated in accordance with the standards for anaerobic lagoons in the Natural Resource Conservation Service (NRCS) Ca lifornia Field Office Technical Guide Conservation Practice Sta ndard Code 359 or othe r applicable standards approved by the APCO, ARB, and EPA.

3.12 Biofilter: a pollution control technique using livin g material to capture and biologically degrade process pollutants. A biofilter is usually a bed of organic material (medium), typically a mixture of compos t and wood chips or shreds.
