Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule 

Amended Rule 1133.1, Chipping and Grinding Activities. Rule 1133.1 aligns the rule with current requirements in place 

by the Local Enforcement Agency (LEA). The rule requires chipping or grinding and utilizing material on-site or removing 

from the site within specified time frames. The material holding time is consistent with state regulations, Title 14, 

Division7, Chapter 3.1 of the California Code of Regulations and is more stringent than the previous holding time 

requirements of Rule 1133.1. Under Rule 1133.1, approximately 70 facilities involving chipping and grinding activities onsite are affected. The rule also provides exemptions for biomass power generation facilities or facilities producing 

biomass fuel for the biomass power generation facilities. 

Adopted Rule 1133.3, Emission Reductions from Greenwaste Composting Operations. Rule 1133.3 implements 

operational best management practices (BMPs) for greenwaste composting operations that produce compost material. 

Approximately 17 existing facilites are affected. The rule requires applying finished compost cover and water to compost 

piles for the first 15 days of the active phase composting to reduce VOC and ammonia emissions. Finished compost 

cover is applied within 24 hours of initial pile formation to each active phase compost pile so that the top is at least six 

inches thick and the pile should not be turned for the first seven days of the active phase of composting. Water should be 

applied, as necessary, to the surface of the pile, within six hours before turning, so that the top one half of the pile is wet 

at a depth of at least three inches for the remaining balance of the first 15 days of the active phase. The rule allows up to 

20 percent manure, by volume, and foodwaste, by weight, to be considered as greenwaste composting. Under Rule 

1133.3, up to 5,000 tons per year of foodwaste can be composted without the need to install an emission control device. 

For more than 5,000 tons per year of foodwaste processing, an emission control device would be required that meets an 

overall system control efficiency of at least 80 percent for VOC and ammonia, respectively, on any active phase compost 

pile containing more than 10 percent foodwaste, by weight. Currently, none of the 17 facilities process more than 2,500 

tons of foodwaste per year. The rule requires recordkeeping and provides limited exemptions.

II. EFFECT ON EMISSIONS 

Complete this section ONLY for rules that, when implemented, will result in quantifiable changes in emissions. Attach 

reference(s) for emission factor(s) and other information. Attach calculation sheet showing how the emission information 

provided below was determined. 

Net Effect on Emissions: Increase Decrease N/A 

Emission Reduction Commitment in SIP for this Source Category: N/A

Inventory Year Used to Calculate Changes in Emissions: 2010 Area Affected: N/A 

Future Year Control Profile Estimate (Provide information on as many years as possible): 

 N/A 

 

Baseline Inventory in the SIP for the Control Measure: N/A

Emissions Reduction Commitment in the SIP for the Control Measure: N/A 

Revised Baseline Inventory (if any): 

Rule 1133.1 seeks to prevent inadvertent decomposition occurring during chipping and grinding activities, including 

stockpile operations, by conforming to applicable state regulations. Previous rule did not have baseline inventory. 

Rule 1133.3 did not have an emission reduction commitment in the SIP and thus the SIP did not propose a baseline 

inventory. However, a baseline inventory was established during the rule development process based on actual 

composting throughput and emission factors. Revised baseline inventory is 2.66 tons of VOC per day and 0.38 tons of 

ammonia per day. 

Revised Emission Reduction Estimate (if developed): 

Rule 1133.1 does not have any emission reduction estimate. 

Rule 1133.3 estimated emission reductions are based on total composting throughput, emission factors, and control 

efficiencies. Emission reduction estimates are 0.88 tons of VOC per day and 0.05 tons of ammonia per day by 2012.

III. SOURCES/ATTAINMENT STATUS 

District is: Attainment Nonattainment Split 

Approximate Total Number of Small (<100 TPY) Sources Affected by this Amendment: 15 facilities 

Percent in Nonattainment Area: 100%

Number of Large (> 100 TPY) Sources Controlled: 2 Percent in Nonattainment Area: 100% 

Name(s) and Location(s) (city and county) of Large (> 100 TPY) Sources Controlled by Rule (Attach additional sheets as 

necessary): 

The attached sheet includes a list of large (≥ 100 TPY) sources of volatile organic compounds (VOCs) controlled by Rule 

1133.3. VOC emissions are from both active and curing phases of greenwaste composting. 

IV. EMISSION REDUCTION TECHNOLOGY 

Does the Rule Include Emission Limits that are Continuous? Yes No 

If Yes, Those Limits are in Section(s) 

Other Methods in the Rule for Achieving Emission Reductions are: Rule 1133.3 (d)(2)(A) - finished compost cover, 

(d)(2)(B) - watering, and (d)(3) - installation of an emission control device for larger foodwate throughput. 

V. OTHER REQUIREMENTS 

The Rule Contains: 

Emission Limits in Section(s): N/A 

Work Practice Standards in Section(s): (d)(2)(B)(i) – squeeze ball test or an alternative 

Recordkeeping Requirements in Section(s): (f) Monitoring Requirements in Section(s): N/A 

Reporting Requirements in Section(s): N/A

VI. IMPACT ON AIR QUALITY PLAN 

 No Impact Impacts RFP Impacts attainment 

Discussion: Rule 1133.3 fully implements Control Measure MCS-04 of the 2007 Air Quality Management Plan (AQMP) 

and would reduce about 0.88 ton of VOCs per day and 0.05 ton of ammonia per day. However, because there was no 

baseline inventory in the SIP associated with this source category, no reductions are being claimed under the 2007 SIP. 

These emissions will be included in the 2012 AQMP baseline inventory.
