Rule Title(s): Solvent Cleaning Operations

Date Submitted to ARB: April 9, 2008

If an Amended Rule, Date Last Amended (or Adopted): July 14, 2006

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

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

The rule amendment delays to January 1, 2009 the co mpliance date for the use of low-VOC (100 g/l) solv ents for

cleaning of ultraviolet or electron beam inks from lithographic printing ink application equipment, fo r the clean up of

on-press screens and screen reclamation using autom atic cleaning equipment. The amendment also expand s the

rule's applicability and proposes new requirements for solvent suppliers.

II. EFFECT ON EMISSIONS

Complete this section ONLY for rules that, when imp lemented, will result in quantifiable changes in em issions. Attach reference(s) for emission

factor(s) and other information. Attach calculatio n sheet showing how the emission information provid ed below was determined

.

Net Effect on Emissions: Increase* Decrease** N/A

Emission Reduction Commitment in SIP for this Sourc e Category: 2.3 tons/day in 2008

Inventory Year Used to Calculate Changes in Emissio ns: 2007 (based on year 2004 currency) Area Affected:

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

Amended Rule 1171 reduces future VOC emissions from solvent cleaning operations by 2.30 tons/day in 20 08 (based on

annual average inventory) by implementing solvent V OC limits beginning January 1 2008 for lithographi c printing using

conventional inks and manual cleaning of screens du ring screen reclamation. However, the amended rule also delays

0.21 ton/day of VOC emissions as a result of extend ing the compliance date for clean up of ultraviolet /electron beam ink

application equipment , on-press cleaning of screen s and screen reclamation using automatic cleaning e quipment.CALIFORNIA AIR RESOURCES BOARD

Baseline Inventory in the SIP for the Control Measu re: 16.0 tons/day for year 2010 Summer Planning In ventory (2003CM

#CTS-10 - Miscellaneous Industrial Coatings and Sol vent Operations)

Emissions Reduction Commitment in the SIP for the C ontrol Measure: NA (fulfillment of technology asse ssment obligation

of ADV-CLNG reductions committed in 1997/1999 SIP)

Revised Baseline Inventory (if any): VOC emissions of 8.01 tons/day in 2007 (based on annual average inventory) from

solvent cleaning operations.

Revised Emission Reduction Estimate (if developed): 2.30 tons/day in 2008 and an additional 0.21 ton/ day in 2009, for a

total VOC emission reduction of 2.51 tons/day for t his amendment (based on annual average inventory). However, the

0.21 ton/day reduction in 2009 from ultraviolet/ele ctron beam ink application equipment and certain sc reen printing clean

up applications is not being submitted yet as part of the SIP, pending review and evaluation of the re sults of the test

program for these applications.

Note that the district’s input to the Rule Evaluati on Form will not be used as input to the ARB’s emis sion forecasting and

planning.

VI. IMPACT ON AIR QUALITY PLAN

No Impact Impacts RFP Impacts attainment

Discussion: Amended Rule 1171 is expected to reduc e VOC emissions by 2.30 tons/day beginning in Janua ry 1, 2008.

The equivalent reductions in the 2007 AQMP currency for 2014 and 2023 are calculated as follows:

2014: 2.25 tpd in 2002 x 1.12 GF = 2.52 tpd in ann ual average

2023: 2.25 tpd in 2002 x 1.24 GF x 1.25 planning i nv./annual average = 3.49 tpd in planning inventory
