If the request for a plan modification is initiated before construction
begins, the stormwater management plan must be resubmitted and reviewed
according to the procedures contained in this chapter.
A. If the request for a plan modification is initiated after construction
is underway, the Municipality Engineer shall have the authority to
approve or disapprove the modification based on field conditions,
provided: the requested changes in stormwater controls do not result
in any modifications to other approved Municipality land use/development
requirements (e.g., building setbacks, yards, etc.); and the performance
standards in this chapter are met. Notification of the Engineer's
action shall be sent to the Municipality of Murrysville Council, which
may issue a stay of the plan modification within five days and require
the permittee to resubmit the plan modification for full stormwater
management plan review in accordance with this chapter.
B. It shall be unlawful to, and no person shall, alter, replace, modify,
landscape or remove, or otherwise adversely affect, any permanent
stormwater management facilities, BMP controls, or any area within
a stormwater easement or dedicated or designated area for stormwater
facilities and BMPs required by an approved stormwater management
plan, or BMP operations and maintenance plan, or to allow the property
to remain in a condition which does not conform to an approved stormwater
management plan, or BMP operations and maintenance plan, unless an
exception is granted in writing by the Municipality and/or approval
is secured from all relevant agencies of the commonwealth.
