B. 
Permits shall be valid for only one site; however, one permit may cover all stormwater control, grading and erosion and sediment control activities on the same site.
C. 
Permits issued pursuant to this chapter do not relieve the owner of the site of responsibility for securing required permits for work to be done which is required by any other applicable code, rule, statutes, regulations or ordinances. This chapter shall not preclude the inclusion in such other permit of more stringent requirements concerning regulation of runoff and erosion.

No person shall violate any conditions imposed as part of a permit.
H. 
Permit expiration and renewal. Every permit shall expire by limitation and become null and void if the work authorized by such permit has not been commenced within six months, is not completed within one year from the date of issue or ceases for a period of six months. The Township may, if the permit holder presents satisfactory evidence that unusual difficulties have prevented work from being started or completed within the specified time limits, grant a reasonable extension of time, and provided that the application for the extension of time is made before the date of expiration of the permit. The Township has the right to attach conditions to permit extensions, including but not limited to the installation/maintenance of erosion control and/or stormwater management facilities.
I. 
Hold harmless indemnity agreement. The Township shall, before issuing a permit, require the applicant to execute an agreement that shall hold harmless and indemnify the Township against any and all suits, claims, losses and damages by reason of the nature of the work such that it may create bodily injury, including death, to person or person or damage to or destruction of property of any kind or character.
