a) Before any deviations from plans and specifications approved by the Agency are made, the owner or official custodian, or an authorized delegate, must make a written request for a supplemental permit. The written request must document all of the changes made to the previously approved plans and specifications. Only those changes identified will be considered for a supplemental permit.

b) Revised plans or specifications must be submitted to and approved by the Agency with the supplemental permit request.

c) The Agency must approve supplemental permit requests if those requests comply with Section 602.105 and this Subpart.

d) A supplemental permit is not required for minor changes that will not affect the location, capacity, hydraulic conditions, water treatment processes or sanitary or mineral quality of the water to be delivered.

e) A supplemental permit will not be granted to add water main after construction has begun, except for additional water main necessary due to a change in the connection point to the existing water distribution system or due to a change in route or alignment. A new application for construction permit must be submitted for water main to serve additional users.
