As a result of the inspection, it is alleged that you have committed probable violations of the Pipeline Safety Regulations, Title 49, Code of Federal Regulations (CFR). The items inspected and the probable violations are: 1. §195.64 National Registry of Pipeline and LNG Operators. (c) Changes.

320185009W_Warning Letter_10042018_text.pdf, page 2(i) Construction or any planned rehabilitation, replacement, modification, upgrade, uprate, or update of a facility, other than a section of line pipe, that costs $10 million or more. Enbridge did not notify PHMSA of the construction of a breakout tank built in Manhattan, IL in 2015. Enbridge began construction of a third breakout tank at the Manhattan terminal in 2015 with a capacity of 491,000 barrels at an estimated cost greater than $10 million. No notice was sent to PHMSA of construction. 2. §195.402 Procedural manual for operations, maintenance, and emergencies. 3. (a) General. Each operator shall prepare and follow for each pipeline system a manual of written procedures for conducting normal operations and maintenance activities and handling abnormal operations and emergencies. This manual shall be reviewed at intervals not exceeding 15 months, but at least once each calendar year, and appropriate changes made as necessary to insure that the manual is effective. Enbridge did not follow its manual of written procedures for corrosion control. Cathodic protection monitoring records showed that the Line 13 casing at milepost 341.69 was electrically shorted to the carrier pipe from 2013 through 2016. PHMSA also observed the casing to be shorted during the inspection on April 13, 2017. Enbridge procedures require that the shorted condition be cleared, however no attempt to clear the short was made. §195.412 Inspection of rights-of-way and crossings under navigable waters. (a) Each operator shall, at intervals not exceeding 3 weeks, but at least 26 times each calendar year, inspect the surface conditions on or adjacent to each pipeline right-of-way. Methods of inspection include walking, driving, flying or other appropriate means of traversing the right-of-way. Enbridge inspected the surface conditions of the Line 13 pipeline right-of-way at intervals that exceeded 3 weeks. Aerial patrol reports showed that the interval between the 3rd and 4th patrol in the annual sequence was not within a 3-week interval during February of 2016.  MP 0-98 – Exceedance by 2 days  MP 98 to 251 – Exceedance by 2 days  MP 251 to Delevan – Exceedance by 2 days  Delevan to Streator takeoff – Exceedance by 2 days  Streator to Manhattan – Exceedance by 3 days 2#
