**body:**

Pursuant to 49 CFR § 195.452(j)(4)(i), DCP Midstream requests a waiver seeking a deferral of integrity assessments required by 49 CFR § 195.452(j)(1) for the Blacklake NGL Mainline Extension 6" (BLK-1 EXT) pipeline, which is due for assessment by 6/21/2021 based on a 5-year assessment interval. The Blacklake Mainline Extension pipeline receives NGL from a single supplier. This supplier has only been able to provide product once a week, and with a volume that limits pig speed to 0.75 mph for approximately the first 20 miles of the segment, based on DCP Midstream’s attempts to perform cleaning runs. This small volume availability from our product supplier is not conducive to an in-line inspection before the regulatory deadline.
