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

Rule 1177 is a newly-adopted rule that will reduce fugitive VOC emissions associated with the transfer and 

dispensing of liquefied petroleum gas (LPG) at residential, commercial, industrial, chemical, agricultural and retail 

sales facilities. The rule applies to the transfer of LPG to and from stationary storage tanks, cylinders and cargo 

tanks, including bobtails, truck transports and rail tank cars, and into portable refillable cylinders. VOC emission 

reductions will be accomplished by requiring the use of low emission fixed liquid level gauges or equivalent 

alternatives during filling of LPG-containing tanks and cylinders, use of LPG low emission connectors, the 

implementation of a leak detection and repair program, along with associated recordkeeping and reporting to 

demonstrate compliance. Rule 1177 will partially implement Control Measure MCS-07 (Application of All Feasible 

Measures) of the 2007 Air Quality Management Plan (AQMP).

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

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: No prior commitment

Inventory Year Used to Calculate Changes in Emissions: 2009 Area Affected: South Coast AQMD

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

It is expected that the 6.1 tons of VOC emissions reduction will be achieved over a five year period beginning July 1, 2013 

and extending until July 1, 2017 when full compliance with Rule 1177 is expected.

2012 AQMP baseline.

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

Revised Baseline Inventory (if any): 8.6 tpd

VI. IMPACT ON AIR QUALITY PLAN

 No Impact Impacts RFP Impacts attainment 

Discussion: The net effect on air quality from the implementation of Rule 1177 is a projected 6.1 tpd reduction in fugitive 

VOC emissions from the estimated 2009 Baseline emissions of 8.6 tpd. It is anticipated that these reductions will be 

accomplished over a five year period as summarized in the table below. This rule partially implements Control Measure 

MCS-07 (Application of All Feasible Measures) of the 2007 Air Quality Management Plan (AQMP).
