BOUNDARY, as determined by monitoring, the permittee shall either (i) demonstrate,
through predictive calculations or modeling, that natural site conditions, facility design and
operational controls will prevent a violation of standards at the Compliance Boundary; or,
(ii) submit a plan for the alteration of existing site conditions, facility design or operational
controls that will prevent a violation of standards at the Compliance Boundary, and
implement that plan upon its approval by the Director.
1. The Permittee or his designee shall inspect the sandstone residual storage, transport, and
disposal facilities to prevent malfunctions and deterioration, operator errors and discharges
which may cause or lead to the release of wastes to the environment, a threat to human
health, or a nuisance. The Permittee shall keep an inspection log or summary including at
least the date and time of inspection, observations made, and any maintenance, repair;, or
corrective actions taken by the Permittee. This log of inspections shall be maintained by the
