Activity Description Forms are available from the Division and shall request the following information: (a) project/activity name and address;(b) proponent's name and address;(c) landowner's name and address;(d) exact location(s) of each activity within the Significant Habitat;(e) description of each activity;(f) type of each activity;(g) commencement and completion dates;(h) signature of proponent and date; and(i) signature of landowner and date.(3) The Director shall respond in writing to such requests within 30 days of receipt of all information required on the form. Failure of the Director to respond within 30 days shall be equivalent to a determination that the proposed activity is not an alteration requiring a permit.(4) The Director shall determine that an activity is an alteration requiring an Alteration Permit if the activity will detrimentally affect the capacity of the habitat to support a population of Endangered or Threatened species.
