If sampling performed by a User indicates a violation, the User must notify the General Manager within twenty four (24) hours of becoming aware of the violation. The User shall also repeat the sampling and analysis and submit the results of the repeat analysis to the General Manager within thirty (30) days after becoming aware of the violation. Resampling by the Industrial User is not required if the South Charleston Sanitary Board performs sampling at the User's facility at least once a month, or if the South Charleston Sanitary Board performs sampling at the User between the time when the initial sampling was conducted and the time when the User or the South Charleston Sanitary Board receives the results of this sampling, or if the South Charleston Sanitary Board has performed the sampling and analysis in lieu of the Industrial User.
