Your Role in the CAT Program
Core Transport Agents (CTAs) are companies or consortia that arrange for the procurement of natural gas on behalf of customers or their own facilities. CTAs activities include purchasing natural gas from producers, arranging natural gas transportation by interstate pipelines and SoCalGas®, as well as balancing natural gas deliveries, storage, and billing for the services.
How to Participate
In order to participate in Core Aggregation Transportation (CAT) Services, you'll need to complete and submit the following documents.
- Core Transport Agent Agreement for Core Aggregation Transportation Service (PDF)
Service agreement CTA must be completed and submitted in order to participate in CAT Service with SoCalGas. Be sure that a duly authorized officer of your company signs this agreement. - Envoy

The CTA uses this attachment to designate appropriate contacts for various CAT services. - Direct Access Service Request (DASR) process (PDF)
This document describes SoCalGas' enrollment/termination process and includes sample DASR submittal and response by SoCalGas. The effective date for an electronically submitted Direct Access Service Request (DASR) for enrollments and terminations that have been submitted is a factor of two items: the cycle read date of the customer and DASR submission date (assuming the DASR has been correctly completed). The general rule is that the DASR effective date will be as soon as the next cycle read date. Per Rule 32, SoCalGas has three business days to process DASRs. - Electronic Billing Information Guide (PDF)
This document describes the flat file document for those CTAs who wish to receive daily billing information electronically. Also, attached is a document that describes the Technical layout (PDF), and also a Sample flat file (PDF) document. In order to receive files electronically the CTA would need to have a FTP site and before testing can commence SoCalGas would need to know the CTA: 1) I.P. address, 2) Login ID, 3) Password, and 4) location to drop off file. The attached documents are in Acrobat .pdf format and total 53k. - In addition to the documents above, potential CTA should refer to pertinent tariff rules located at the SoCalGas tariff information page, which are: Rule 32 (Core Aggregation Transportation), Rule 36 (Interstate Capacity Brokering), Rule 30 (Transportation of Customer-Owned Gas), Sch G-IMB (Transportation Imbalance Service) and Sch G-CBS (UDC Consolidated Billing Option).
