DOW PIPELINE LLC — Integrity Assurance Notification

REPAIRThis letter is being submitted by Dow Pipeline Company, a wholly owned subsidiary of The Dow ChemicalCompany (Dow) in accordance with 49 CFR §195.452(h)(1)(i) to notify OPS of a delay in repair of a 60-day condition and a 180-day condition, as defined in §195.452(h)(4). Following an in-line inspection of Dow’s GCPL_SH_12IN pipeline, it was determined on May 27, 2019 that there was a potential 60-day and 180-day condition at approximately 20-feet from the bank under the San Bernard River. Due to the location of the called anomaly, Dow contacted the U.S. Army Corp of Engineers for a permit to repair or replace the pipeline. Given the logistics of the repair, Dow anticipates that the timing to receive the permit from the USACE and to repair the condition will be 6-8 months.#
