7. If a CEC has not been obtained, please provide:

A conceptual Storm-water Management Plan for the site stating:

 The temporary and permanent measures that will be implemented during the site preparation, construction and post-construction phases to

ensure that there is no net increase in peak runoff for a 1:25 rainfall event from the pre-development to the post-development phase

 The pre-development flow value (Q m3/s) for the proposed site such that the existing volume of surface runoff for the site can be quantified

 The description of any onsite measures that would be instituted to maintain the pre-development flow value during the construction and post-

construction phases of the proposed development

 The proposed storm-water management measures can accommodate the post-development flow value and reduce it to the pre-development

flow value (Q m3/s)

 Calculations for determining the pre-and post-development flow value (Q m3/s) for the proposed site

 The drainage mechanisms

 The storm-water retention/detention ponds, catchments, landscaping, etc

 The proposed plans for the inspection and maintenance of any physical structures (e.g. detention/retention ponds, catchments, etc.) that may

be constructed on the site.

ii.

A Sediment and Erosion Management Plan for the site stating the:

 Temporary and permanent measures that will be implemented during the site preparation, construction and operational phases of the

development

 Possible measures such as, but not limited to, phased clearing, settling pond(s), filtering devices placed within drains and re-vegetation, that

will be implemented to minimise or prevent the movement or migration of sediments off site due to the proposed site activities.

iii.

A Monitoring and Reporting Plan for the Quality of Water Discharged from the site

iv.

The Mitigation Measures to be applied for dust pollution, noise pollution, emissions from equipment/vehicles, soil pollution, and fuel and oil

spills
