Details: SUMMARY: we held our conference call this morning DETAILS: 1.In your email, you offered to address this situation with a letter reminding OPRD that residuals must be recorded every day and requesting that reporting be completed appropriately for the next three months. This letter would be directed to the operator of record for the system. This approach sounds great to us and we appreciate this consideration. Please copy the group listed on this email for that letter. My hope is that the remainder of the items in this email will identify the steps we have taken and will take to address this in the future.2.Clarified triggering events. Previous bacteria results in our source well mean we need to provide “4-log treatment”. For our system at Humbug, “4-log treatment” means maintaining a residual of 0.3 mg/L at the entry point to the distribution system. This is the critical compliance point that will trigger whether a public notice needs to be posted or not. We don’t drop below 0.3, we don’t post. We drop below 0.3, we post (see exception noted below).3.For internal purposes, a residual level of 0.5 will trigger a review of dosage levels, with adjustments as needed. Goal is to begin dosage adjustment process well before the compliance limit of 0.3 is reached.4.Notices will be posted locally within 24 hours of failure to maintain appropriate residual and sent to Brody as soon as possible thereafter. ACTION NEEDED: 12.Process issues – We believe we have clarification on process, testing, and reporting issues that will address the vast majority of previous compliance issues.Source quality issues – We have started a path we believe will identify the source issues and a corrective plan. When that plan is identified and if it results in addressing the source of well bacteria readings, we may approach Brody for direction on modifying our 4-log treatment requirement
