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

The proposed rule will establish a depressurization limit of less than two pounds per square inch gauge (psig) 

pressure prior to venting a coke drum to atmosphere and includes options for alternative compliance schedules 

for facilities not able to meet the rule compliance timeline, depending on the number of delayed coking units they 

operate. The proposed rule also includes deadlines for permit applications and installation of monitoring 

equipment and downtime notification provisions, recordkeeping provisions and exemptions from certain 

Regulation IV requirements. 

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: No prior commitment 

Inventory Year Used to Calculate Changes in Emissions: 2010 Area Affected: SCAB 

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

VOC emission reductions are expected beginning November 1, 2013, achieving 129, tons per year in January 1, 2019, 

when Rule 1114 will be fully implemented.

VI. IMPACT ON AIR QUALITY PLAN 

 No Impact Impacts RFP Impacts attainment 

Discussion: The net effect on air quality from the implementation of Rule 1114 is a projected 0.35 tpd reduction in VOC 

emissions from the estimated 0.73 tpd baseline inventory.
