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

Amended Rule 1133.1, Chipping and Grinding Activiti es. Rule 1133.1 aligns the rule with current requi rements in place

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

from the site within specified time frames. The ma terial holding time is consistent with state regula tions, Title 14,

Division7, Chapter 3.1 of the California Code of Re gulations and is more stringent than the previous h olding time

requirements of Rule 1133.1. Under Rule 1133.1, ap proximately 70 facilities involving chipping and gr inding activities onsite are affected. The rule also provides exemptio ns for biomass power generation facilities or facil ities producing

biomass fuel for the biomass power generation facil ities.

Adopted Rule 1133.3, Emission Reductions from Green waste Composting Operations. Rule 1133.3 implement s

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

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

piles for the first 15 days of the active phase com posting to reduce VOC and ammonia emissions. Finis hed compost

cover is applied within 24 hours of initial pile fo rmation to each active phase compost pile so that t he top is at least six

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

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

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

20 percent manure, by volume, and foodwaste, by wei ght, to be considered as greenwaste composting. Un der Rule

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

For more than 5,000 tons per year of foodwaste proc essing, an emission control device would be require d that meets an

overall system control efficiency of at least 80 pe rcent for VOC and ammonia, respectively, on any act ive phase compost

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

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

II. EFFECT ON EMISSIONS

Complete this section ONLY for rules that, when imp lemented, will result in quantifiable changes in em issions. Attach

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

provided below was determined.

Net Effect on Emissions: Increase Decrease N/A

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

Inventory Year Used to Calculate Changes in Emissio ns: 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 Measu re: N/A

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

Revised Baseline Inventory (if any):

Rule 1133.1 seeks to prevent inadvertent decomposit ion occurring during chipping and grinding activiti es, including

stockpile operations, by conforming to applicable s tate regulations. Previous rule did not have basel ine inventory.

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

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

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

ammonia per day.

Revised Emission Reduction Estimate (if developed):

Rule 1133.1 does not have any emission reduction es timate.

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

efficiencies. Emission reduction estimates are 0.8 8 tons of VOC per day and 0.05 tons of ammonia per day by 2012.CALIFORNIA AIR RESOURCES BOARD

III. SOURCES/ATTAINMENT STATUS

District is: Attainment Nonattainment Split

Approximate Total Number of Small (<100 TPY) Source s 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 (VO Cs) controlled by Rule

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

IV. EMISSION REDUCTION TECHNOLOGY

Does the Rule Include Emission Limits that are Cont inuous? Yes No

If Yes, Those Limits are in Section(s)

Other Methods in the Rule for Achieving Emission Re ductions are: Rule 1133.3 (d)(2)(A) - finished com post cover,

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

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 the re was no

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

These emissions will be included in the 2012 AQMP b aseline inventory.Attachment: A List of Large (≥100 TPY) Sources for VOCs and Ammonia Controlled by Rule 1133.3FacilityIDFacilityNameLocationStreetLocationCityLocationStateLocationZipVOCEmissions(TPY)AmmoniaEmissions(TPY)151839AGROMIN-NEWHALL26835 Pico Canyon Road,End of Potrero Canyon RoadNEWHALLCA91381172.7924.42139109BAKER CANYON GREEN RECYCLING27910 Baker Canyon RoadSILVERADOCA92676467.0066.00
