Subsection 2 presents the results of monitoring of the companies activities during the period under review,
including scientific and technical data.
Subsection 3 discusses the results, their interpretation, and their significance for the environment in the
immediate vicinity of the site under discussion.

Each company’s activity is then discussed in a separate section (Sections 2 to 7).
In the subsections for each company (e.g. Section 2.1) there is a general description of the industrial activity
and its discharges, an aerial photograph or map showing the location of the activity, and an outline of the
matters covered by the company’s air discharge permit.
Subsection 2 presents the results of monitoring of the company’s activities during the period

Subsection 2 presents the results of monitoring of the
water monitoring. The removal of hydrocarbon related products reduces
risk in these areas significantly. The odour issue is well understood and with correct
operational techniques applied can be well controlled.

respondents had visited one of these sites in the last year. Figure 2 represents the most
popular coastal, river or lake destinations for residents from the New Plymouth,
