Gas Pill

66.

66.

Please confirm the proposed gas pill does not require an ERA. Please provide details of
screening of the gas storage facility to nearby buildings and safety precautions and size of
the storage facility.

QANTEC McWILLIAM has advised that the proposed gas pill has a capacity of 3 tonnes and
is approximately 7 metres x 1 metre. Accordingly, an ERA is not required.

Sketches of the proposed screening measures are included as Attachment 22.

It is noted that AS1596 requires the a gas pill of this size to provide open access along the
length of at least one side, with no barrier on this side for a minimum of 14 meters. The gas
pill has a length of 7 metres and accordingly it must be separated from adjacent walls by a
minimum of 7 metres. Furthermore, it is noted that the wail adjacent to the adjoining duplex
dwelling is required to have a 4.5 hr fire rating.

Contaminated Area

67. Please provide details on the removal of contaminated material from the site. The timing of

67.

these works as well as the management requirements needed to them should be detailed.

The applicant has liaised with the Environmental Protection Agency (EPA) regarding the
removal of the contaminated material from the site. Currently, the Draft Remediation Action
Plan (RAP) has been submitted to the third party reviewer, and the applicant is awaiting a
decision from the EPA.

It is anticipated that the contaminated cell shall be removed prior to the commencement of
any works associated with this application. Removal of this material shall be done in
accordance with the conditions of the approval given by the EPA.

Freshwater Habitat

68. Please detail the proposed distance between the edge of the water mark and Block C. The

68.

freshwater habitat has requirements for plantings of shrubs and tufted grasses around its
edge for a minimum width of 3 metres. The Environmental Management Plan also notes that
Native trees surrounding the pond will provide perches for birds and shade over part of the
water body. The proximity of the C Block would appear to inhibit the growth of trees and
Shrubs.

The CAS did not include a condition requiring a 3 metre setback from the Freshwater Habitat.
