Items of interest from this month's meetings of two of the Council's key committees, Consents & Regulatory, and Policy & Planning: Clear thinking needed on clean waterThe Council has urged the Government to go back to first principles and clearly identify the nature of any problem before finalising its latest freshwater management proposals. In a submission approved by the Policy and Planning Committee, the Council says the Government needs to clarify and refine the definitions used in its
things that put pressure on our freshwater.
"No one is removing the hydro-dams that interfere with flow
of sediment, fish and water, but also generate clean and
renewable energy, help to manage flooding, and provide a
world-class rowing lake. We’re not removing the roads and
paved cities that flood rivers with contaminated storm water.
We’re not closing down agriculture, but we do expect lower
footprint farming systems. Can we really expect to be able to
have our cake and eat it too?”
thickness, permeability, expected reservoir
pressure and location within the well and is established based on data obtained
during the drilling process (open-hole logs). The hydraulic fracture stimulation is
designed to cover the entire height of the sand interval with proppant and should
extend away from the well to the desired fracture half length in order to optimise
productivity gains. Typical proppant filled fractures in Kapuni are a height of 10
to 30 m and an effective fracture half length
considered, such as poor visibility and
slippery roads when driving; power cuts affecting heating, cooking and life saving medical
equipment; electric shock due to wet ash being conductive; contamination of water supplies
and water shortages; sewerage facilities not functioning creating sanitation problems; people
falling from building roofs when cleaning ash (which has proved fatal for a significant number
of people following eruptions); and roof collapse from the weight of ash (see below).

lake [5801] and to discharge stormwater from road surface drainage into the lakes

In January 2008, a reconditioned gas fired furnace was installed which replaced the
previous gas fired melting and holding furnaces. Only clean scrap is loaded into the
new gas furnace, which discharges directly

follow the Check, Clean, Dry method every time they move between waterways. “It just takes one fragment the size of a fingernail to cause a new infestation. If people are not vigilant in cleaning their gear it will inevitably spread and then we’re fighting a losing battle. “Once a weed such as hornwort becomes established in a lake or waterway the cost and logistics make it almost impossible to eradicate. That’s why our focus has to be on prevention.” The Council is working closely with South

Introduction
Process description
Dialog Fitzroy Ltd carries out abrasive blasting to clean and prepare surfaces for painting. The process
involves blasting garnet, an abrasive sand-like substance, onto the surface of the object in question. Material
from the blasting process becomes airborne due to the release of high pressure air used to accelerate the
abrasive media to the required cleaning velocities. Spray painting is also carried out on the site. The
company holds air
inspections of
the site and surrounding environment, at approximately fortnightly intervals. In total 9
stormwater samples were collected for chemical analysis.
The monitoring showed that, in general, reasonable processes and procedures were
implemented. A strong focus on the environment by all personnel ensured that the site was
mostly clean and tidy.
Any spills on-site were quickly cleaned up to avoid the potential for a contaminant to travel to
surface water. The site’s stormwater system
