The council issues resource consents for the earthworks and water use needed in alluvial goldmining and it deals with recurring complaints about creeks running dirty, allegedly from mining operations.
That keeps West Coast Regional Council compliance staff on the hop — checking out the cause and making site visits to see if miners are sticking to the conditions of their consents.
The gold price was likely to attract new players inexperienced in running alluvial mining sites, he said.
The council’s latest compliance report shows five goldminers were pinged with enforcement action — usually an infringement notice and fine — for failing to keep to the rules.
Two were exceeding the area they were allowed to dig up; one had dug a bigger pit than his consent allowed; and two had caused dirty water or sediment to flow into local waterways.
One repeat offender was now before the courts.
But not all complaints about goldmining were well-founded.
One about an access road being built had involved private land and breached no rules.
Three more, about dirty water in Waimea Creek, the Little Grey River and at Awatuna, proved groundless — or not the fault of miners.
In another case, dirty water leaching from an old mining tunnel was fixed on the spot by the current miner, who sealed it off with gravel.
People were entitled to raise concerns about pollution of waterways, but should bear in mind staff time and travel were involved, Cr Cummings said.
"We’re still getting a lot of complaints that turn out to be minor or not significant. People have a right to complain, but they should be aware that these staff visits are all costing the ratepayers."
Council chairman Peter Haddock, a retired gold-miner, confirmed to LDR the council was upping its compliance game, with a focus on repeat offenders, and not just in goldmining.
It recently hired former police officer Chris Maitland on a fixed-term contract to beef up its investigations.
Cr Haddock said prosecutions were a last-ditch measure. Council policy was first to engage with consent holders, educate them, empower them — and if all else failed — enforce.
Education was the key to ensuring the expected newcomers to goldmining, and some old-timers, kept to the rules, he said.
He said last week council took five compliance staff on a tiki tour of alluvial gold-mining sites to show them what good practice looked like.
The council was also looking to upskill miners — and new ones in particular, he said.
"We are working with Minerals West Coast to hold workshops for consent holders, using experienced miners to help and advise them."
The workshops planned for later this year would focus on gold-miners in the Waimea catchment northeast of Hokitika, the area that generated more than its share of complaints about water quality, Mr Haddock said.
There are other signs the openly pro-development council is getting tougher with polluters.
It recently prosecuted one of the West Coast’s major industries — CMP Kokiri (Anzco Foods).
The beef processor pumps $133million into the West Coast economy annually and employs 190 people.
But staff reports describe the company’s yearly environmental self-reports as "not being credible for the past three years."
It will be sentenced next month for discharging contaminants to water.
