55 GPCD is the performance standard for indooruse (78 suppliers representing about 9.5 millionpeople are reporting less total use in December)

High R-GPCD plus low percentage reduction

raises questions about factors inhibitingconservation response

Next Steps

Continue working with suppliers to achieve compliancewith emergency regulation

Evaluate recommendations from December 17workshop and written comments

Present an Information Item at February 17-18 BoardMeeting focused on potential options for next steps-Including: Extending and/or augmenting current emergency

regulation before April 2014 expiration date

Funding Opportunities Focused/location specific use of other authorities
