1459.006 EXEMPTIONS.
   An exemption shall not relieve the applicant from implementing the requirements of this chapter or from implementing such measures as are necessary to protect public health, safety, and property. An exemption shall not relieve the applicant from complying with the special requirements for watersheds draining to identified high quality (HQ) or exceptional value (EV) waters or any other current or future State or municipal water quality protection requirements. If a drainage problem is documented or known to exist downstream of, or is expected from the proposed activity, then the Borough may withdraw exemptions listed in Table 106 and require the applicant to comply with all requirements of this chapter. Even though exempt, the applicant is not relieved from complying with other Borough ordinances or regulations.
   (a)   General Exemptions.
      (1)   Table 106.1 summarizes the exemptions from certain provisions of this chapter. Exemptions are for the items noted in Table 106.1 only, and shall not relieve the applicant from other applicable sections of this chapter.
      (2)   Any regulated activity that is exempt from some provisions of the chapter is exempt only from those provisions. If development is to take place in phases, the developer is responsible for implementing the requirements of the chapter as the impervious cover/earth disturbance threshold is met. The date of the chapter adoption shall be the starting point from which to consider tracts as "parent tracts" in which future subdivisions and respective impervious area and earth disturbance computations shall be cumulatively considered. Exemption shall not relieve the applicant from implementing such measures as are necessary to protect health, safety, and property. For example:
 
If a property owner proposes a 150 square foot shed after adoption of the municipal stormwater management chapter that property owner would be exempted from water quality and quantity requirements of the chapter as noted in Table 106.1 of the chapter. If, at a later date, the property owner proposes to construct a 499 square foot room addition, the applicant would be required to comply with the requirements for the Simplified Method for the full 649 square feet of impervious cover created since adoption of the Borough ordinance. If an additional 700 square foot swimming pool/patio is proposed later, the property owner would be required to implement the full stormwater quantity and quality control submission requirements of this chapter for the total 1,349 square feet of additional impervious surface added to the original property since adoption of the Borough ordinance.
