Upset in the refinery's cooling water systems resulting in the apparent exceedance of the VOC emission rate limit due to mechanical failure within a set of heat exchangers which resulted in releasing VOCs into the cooling water system. No DEQ report in this file, follow-up letter only.
VOCs stripped in the cooling water tower and emitted to the atmosphere in cooling tower exhaust, samples taken at the battery limits of multiple units until source was identified, isolated heat exchangers to minimize hydrocarbon carryover across cooling water system
