k. 50 feet between high rate infiltration unit and property lines,
1. 50 feet between treatment units and property lines, and
m. 50 feet between high rate infiltration unit and public right of ways.
Some of the buffers specified above may not have been included in previous permits for this
waste treatment and disposal system. These buffers are not intended to prohibit or prevent
modifications, which are required by the Division, to improve performance of the existing
treatment facility. These buffers do, however, apply to modifications of the treatment and
disposal facilities, which are for the purpose of increasing the flow that is tributary to the facility.
These buffers do apply to any expansion or modification of the high rate infiltration areas and
apply 'in instances in which the sale of property would cause any of the buffers now complied
with, for the treatment and disposal facilities, to be violated. The applicant is advised that any
modifications to the existing facilities will require a permit modification.
