I. GENERAL INFORMATION 

District: Great Basin Unified Air Pollution Control District

Rule No(s): 433 Date adopted/Amended/Rescinded: April 13, 2016

Rule Title(s): Control of Particulate Matter Emissions at Owens Lake

Date Submitted to ARB: ______________

If an Amended Rule, Date Last Amended (or Adopted): NA

Is the Rule Intended to be Sent to the U.S. EPA as a SIP Revision? X Yes No (If No, do not complete remainder of form) 

District Contact: Duane Ono Phone Number: (760) 872-8211 E-mail: dono@gbuapcd.org

Address: Narrative Summary of New Rule or Rule Changes: X New Rule __ Amended Rule

The purpose of this regulation is to provide a regulatory mechanism under the federal Clean Air Act to attain the NAAQS and

to implement the 2014 Stipulated Judgment between the District and the City of Los Angeles. It requires the City to

implement BACM to mitigate windblown dust at Owens Lake, CA, to operate and maintain the existing control area, and if

ordered, to control additional areas provided that the amount of District-ordered dust control areas on the lake bed does not

exceed 53.4 square miles in total.

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

(CO) X 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 X Decrease N/A

Emission Reduction Commitment in SIP for this Source Category: 1,581 tons per year of PM10 is expected to be reduced 

from lake bed areas as a result of new BACM measures. 

Inventory Year Used to Calculate Changes in Emissions: 2014 (actual lake bed emission estimate)

Area Affected: Owens Lake bed

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

Year Tons of PM10/yr

2014 1,936

2015 1,936

2016 1,222

2017 1,222

2018 355

2019 355

Baseline Inventory in the SIP for the Control Measure: 1,936 tons/yr of PM10

Emissions Reduction Commitment in the SIP for the Control Measure: 1,581 tons/yr of PM10

Revised Baseline Inventory (if any): 

Revised Emission Reduction Estimate (if developed): 

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 X Split

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

Percent in Nonattainment Area: NA % 

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

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

necessary): NA

IV. EMISSION REDUCTION TECHNOLOGY

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

If Yes, Those Limits are in: Rule 433 Attachment A

Rule 433 sections A.2, B, and Attachment A require BACM to be implemented continuously in all dust control areas on the 

Owens Lake bed during the dust season from October 1 through June 30, except for areas that are eligible for the Dynamic 

Water Management Program and may have shorter dust control periods. For BACM areas, the rule requires 99% control 

during dust season, except for Minimum Dust Control Efficiency Areas identified in the 2008 SIP that may have lower dust 

control efficiencies based on the model attainment demonstration. 

V. OTHER REQUIREMENTS 

The Rule Contains: 

Emission Limits in Section: Att. A Work Practice Standards in Section: Att. A

Recordkeeping Requirements in Section: Att. A Reporting Requirements in Section: Att. A
