# Background/Implementation ► 

# Control T

echniques Guidelines (CTG): ► 

# Provide guidance to state, local and tribal air agencies to assist them in determining reasonably available control technology for volatile organic compounds from select sources. ► 

# Applies to existing sources in ozone moderate, and higher, nonattainment areas and the Ozone Transport Region (OTR). • Currently 151 counties are designated moderate or higher 

# • States in OTR - VA , P A, DC, MD, DE, NJ, NY , VT , NH, MA, RI, CT , ME 

# ► 

# States are required to submit revisions to their state implementation plans after a CTG is finalized. ► 

# Ti meline set when CTG is finalized ► 

# Ty pically given one year to submit revisions ► 

# States have flexibility to adopt RACTrecommendations or can use them to inform their own determination.

# Summary of RACTRecommendations ► 

# Storage vessels ► 

# Across source category ► 

# Ninety

five percent reduction of VOC emissions from storage vessels with potential to emit greater than 6 tpy ► 

# Compressors ► 

# Production and processing, excluding well site ► 

# Centrifugal Compressors • Wet seal – Reduce VOC emissions by 95% 

# • Dry seal – not covered ► 

# Reciprocating Compressors • Reduce VOC emissions by replacing rod packing after 26,000 hours of operation or 36 calendar months, or 

# • Route emissions from the rod packing to a process through a closed vent system under negative pressure 

# ► 

# Pneumatic controllers ► 

# Natural gas processing plants • Natural gas bleed rate of zero standard cubic feet per hour ( scfh ) ► 

# We llhead to natural gas processing plant • Natural gas bleed rate less than or equal to 6 scfh

# Model Rule ► 

# CTG includes model rule language ► 

# Provides example regulatory text for air agencies to use in writing enforceable requirements ► 

# Includes: ► 

# Key definitions ► 

# Identification of af

fected facilities (applicability) ► 

# Emission control requirements ► 

# Compliance and test methods ► 

# Recordkeeping, reporting and monitoring ► 

# Based on approach included in other CTG documents (e.g. Coating Operations at Aerospace Manufacturing and Rework Operations (December 1997))

# Estimate of Reductions and Cost ► 

# Potential emission reductions: ► 

# VOC – 23,392 tons per year ► 

# Methane – 4,842 tons per year ► 

# HAP – 734 tons per year ► 

# Potential costs: ► 

# Capital - $446M ► 

# Annual (without savings) - $278M ► 

# Annual (with savings) - $206M ► 

# Based on current ozone moderate, and higher, nonattainment areas and the OTR.
