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

To further reduce particulate emissions, the amendment requires additional control measures, such as: threesided barrier with a roof and wind fence, tarps, and barriers/wind fences for clinker piles. 

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2 

 (CO) PM TAC (name): 

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: Rule 1156 and Rule 1157 (Aggregates) were 

adopted to implement Control Measure BCM-08 of the 2003 AQMP. That control measure called for a 0.7 tons per 

day (tpd) PM10 reduction by December 31, 2010 off of a 1.7 tpd emissions baseline inventory. The Rule 1156 portion 

of BCM-08 baseline inventory was 0.4 tpd PM10 with an emission reduction contribution of 0.2 tpd. This is what was 

reported for SIP purposes, which was approved by the EPA in March 2008.

However, during the Rule 1156 development process, the inventory baseline and reductions were updated. The 

revised emissions inventory of 2.1 tpd PM10 (4.2 tpd total PM) in 2003 was reduced through rule implementation by 

1.1 tpd PM10 (2.2 tpd of total PM). This information was used to update the emission inventories for this source 

category in the 2007 AQMP. (Note: the 2007 AQMP does not contain any additional emission reduction commitments 

for this source category).

These amendments to Rule 1156 will achieve emission reductions of 0.04 tpd PM10 (0.006 tpd PM2.5, 0.09 tpd total 

PM) and are in addition to the revised reductions now reflected in the 2007 AQMP.

Baseline Inventory in the SIP for the Control Measure: The 2007 AQMP emission inventories contain the aforementionned 

revised emissions inventory data.

Emissions Reduction Commitment in the SIP for the Control Measure: The 2007 AQMP contains no additional emission 

reduction commitment for this source category.

Revised Baseline Inventory (if any): Not applicable. 

Revised Emission Reduction Estimate (if developed): The estimated additional emission reductions for the Rule 1156 

amendment are 0.006 tpd PM2.5, 0.04 tpd of PM10 and 0.09 tpd of total PM. 

Note that the district’s input to the Rule Evaluation Form will not be used as input to the ARB’s emission forecasting and 

planning. 

III. SOURCES/ATTAINMENT STATUS

District is: Attainment Nonattainment Split 

Approximate Total Number of Small (<100 TPY) Sources Affected by this Amendment: N/A

Percent in Nonattainment Area: N/A% 

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): 1) TXI Riverside Cement (TXI) near the city of Riverside in Northeastern Riverside County; and 2) California 

Portland Cement Company (CPCC) near the city of Colton in Southwestern San Bernadino County.

IV. EMISSION REDUCTION TECHNOLOGY

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

If Yes, Those Limits are in Section(s) of the Rule. 

Other Methods in the Rule for Achieving Emission Reductions are: The amendments focus on clinker material handling 

and storage by requiring: three-sided barrier with a roof and wind fence, tarps, and barriers/windfences to further reduce 

particulate emissions. The amendment also includes other requirements listed in Section V below to ensure public health 

protection. Since these requirements do not generate quantifiable emission reductions, the following sections are not

submitted for SIP approval: (d)(10), (d)(11), (d)(12), (d)(13), (f)(2)(F), (f)(2)(G), and (f)(3).

V. OTHER REQUIREMENTS

The Rule Contains: 

Emission Limits in Section(s): (d)(11)(A) , (d)(11)(B), (d)(12), and (d)(13)(B); however, they are not part of the SIP 

submittal. Work Practice Standards in Section(s): (d)(11)(A) , (d)(11)(B), (d)(12)(A), and (d)(13).

Recordkeeping Requirements in Section(s): (f)(2)(F) and (f)(2)(G) Reporting Requirements in Section(s): (f)(3)

VI. IMPACT ON AIR QUALITY PLAN

 No Impact Impacts RFP Impacts attainment 

Discussion: The amendment would reduce an additional 0.006 tpd PM2.5, 0.04 tpd of PM10 and 0.09 tpd of total PM from 

this source category, and contribute towards attainment of the 24-hour PM 2.5 and PM10 standards.
