This may be due to damage to the piping or discharge structure. But as such, this basin would still be subject to analytical monitoring and would not meet requirements to be considered secondary containment. It was also observed that a large area of the site (including the areas dirrecly beneath the add/mix storage area, at least partially bypasses the pit and drains directly to a diversion ditch on the South side of the site. This diversion also appeared to occasionally allow water to overtop and discharge from the south side of the facillity (see attached pics). For your proposed approach to secondary containment and analyical discharge: The permittee will need to modify the current infrastructure at the facility and demonstrate that the basin does not have a constant discharge to provide all required secondary containment. The permittee will need to demonstrate that the basin does not have a constant discharge to be exempt from Analytical Monitoring. washwater flowing to the south end of the site. Overview showing the direction of flow. A spill would follow the same path as the washwater and could potentially end up in the basin and become a release due to the basins constant discharge. Photo showing how full the basin was during the visit. Below is an image of the oulet pipe from the basin discharging and flowing out from the bottom right corner of the image. , , r , _ l a.

Isaiah, I received a copy of the report for the inspection that you did at our Morganton Plant (COC NCG140410) on February 2, 2021. 1 subsequently met onsite with Robert Canipe and Tim Glazebrooks on February 25t" to review your findings. It is our opinion that this site is exempt from analytical monitoring requirements per Part IV, page 1 of NCG140000 because the detention pond that captures all flow from this site was designed to contain a 25-year, 24-hour storm event. This engineering design and documentation was submitted with the original permit application. We also believe that secondary containment of chemical admixtures beyond the present sea containers is unnecessary since any spillage would drain to the wash pits and any overflow from there would be captured in the detention pond. All other documentation including training and qualitative monitoring was discussed with Tim and Robert will be current going forward. If you have any questions or would like to meet with me or Robert onsite on or after April 6t", please let me know.
