Joe, Juan is going to help with identifying the appropriate seals for the piping penetration. He has the plans from a similar effort that was developed back in 2012. It’s not clear whether this effort was carried out. He would like to arrange a field visit with the black light to look and see if they did any of the construction from the plans he has.

Michael Spitz, PE Civil/industrial Engineer FRCE Facilities & Infrastructure Design Section Ph: 252.464.9969

Joseph, During the site visit we noticed that the sealing elements of the pipe penetration systems used on the pipes penetrating the cyanide secondary containment has deteriorated significantly. Seals installation circa 2012. The pipe sleeves and concrete surface appear to be in good conditions.

We recommend replacing the sealing element for each of the three (3) penetrations. Wall sleeves and piping may be re-used. Refer to enclosed sketch for additional details.

As discussed with FRC East Environmental Department, sumps are to be emptied by FRC East HAZMAT team. The hazardous conditions of the work area warrant the selected contractor to comply with specific occupational safety and health requirements. Contractor must obtain a Confine Space Entry permit in accordance with FRC East Instruction “FRCEASTINST 5100.14C_Confine Space Entry Program”. Also, Contractor must use Personal Protective Equipment (PPE) suitable for hazardous environment in accordance with FRC East Instruction “FRCEASTINST 5100.2 Occupational Safety and Health Manual”.

If you have any questions or require additional input or investigation on my part, please contact the Facilities and Infrastructure Design Team at your convenience.
