This Supplemental Environmental Assessment (EA) evaluates the environmental effects of the proposed international border crossing at the southern terminus of the already permitted Southern California Gas Company (Gas Company) line 6902. The new, proposed project is called the Line 6902 El Centro to Mexicali Project ... The original EA for SoCalGas Line 6902, prepared for the BLM, was issued in September 1993. This proposed revision to the 77.6 mile-long line 6902 would increase net mileage 1.5 miles and move the border crossing 1.7 miles to the east.
