For the Oregon Beer Growler
“The single most important ingredient in craft beer is water,” Environmental Protection Agency administrator Gina McCarthy told brewers at the Craft Brewers Conference held in Portland in April. Not exactly a news flash. But, her comments about why they should support clean water were.
A little background: The 1972 Clean Water Act was diluted by Supreme Court rulings in 2001 and 2006 that seemed to exclude certain bodies of water. Therefore, the EPA and the Army Corps of Engineers drafted the Clean Water Rule to define the included water bodies. They released the rule in March 2014 for public comment, hoping for final adoption this summer.
“Before the new rule, up to 60 percent of American streams and millions of acres of wetlands were potentially overlooked by the Clean Water Act,” EPA officials said.
The Natural Resources Defense Council or NRDC, a nonprofit environmental organization, invited brewers to support the Clean Water Rule by taking the Clean Water Pledge.
Karen Hobbs, from the NRDC, said about 70 brewers have taken the pledge so far. By doing so, they sign on to comment letters to senators and the president and they are listed on the NRDC website as a partner to defend the Clean Water Act.
“What they do next is up to them,” said Hobbs. Many have improved efficiency at their facilities, engaged in watershed cleanups and improved water use. “Still,” Hobbs said, “we’re looking for ways to work better with the craft brewers because they are so embedded in their communities and so directly affected by local water. Many of them have amazing outreach in their communities.”
Like Bear Republic Brewing Company in Sonoma County, Calif. Peter Kruger, master brewer, said the brewery, established in 1996 in Healdsburg, Calif. broke ground on a new facility in Cloverdale, Calif. in 2006 with the idea there was plenty of water for the expansion. “We soon realized there wasn’t enough for the city, let alone our brewery.”
The city wanted to drill two new wells, but faced a five-year wait to secure loans from the United States Department of Agriculture. Bear Republic then fronted the city $475,000 in impact fees. Now they have two new wells with a million gallons of excess capacity. Peak demand is 1.8 million but the wells can pump 2.8 million.
Kruger said, “These were fees we planned on paying anyway. The amount we paid is what we estimated we needed to grow our brewery — basically we prepaid about eight years of fees,” he said.
With the money from Bear Republic, the city of about 8,000 people was able to fast track the wells. The brewery has introduced processes to conserve water in its drought-stressed region. “We run an incredibly low water ratio to beer, 3.5 gallons-to-1 gallon of beer. If you take out the water for office and irrigation use, it’s 3.1-to-1,” said Kruger.
The brewery has invested in technology to monitor water use and increase efficiency. They have spent several million dollars on an anaerobic digester that will treat wastewater.
In the first step, water runs through the digester and organic matter decomposes to methane, which will be burned for electricity. The exhaust gas preheats the processed water and will meet about half of their plant’s hot water needs. Then the water will run to the aerobic digester that will clean it up through a reverse-osmosis process for reuse in cleaning and wash downs. Kruger expects this to be up and running by January.
“Brewers are in a unique position to influence the world with the Clean Water Pledge,” he said.
Many leaders in the Brewers for Clean Water come from the water-challenged West.
Jenn Vervier, from New Belgium Brewing in Colorado, wrote a persuasive editorial in support of the Clean Water Rule in 2012 called “Clean Water is Good for Business and Beer.”
Closer to home, HUB recently signed the Clean Water Pledge and is working with the NRDC to develop some educational opportunities around the pledge.
Water conservation is a top priority at HUB. A recently installed custom cleaning-in-place skid allows reuse of the cleaning solution up to five times while maintaining water temperature and chemical effectiveness. A new centrifuge yields more beer per tank and uses less water for cleaning.
Outside, there are pervious pavers in the upper parking lot and the lower lot is sloped to catch water in a retention pond, allowing rainwater to become groundwater.
“Our heat exchange unit allows us to capture city water and use it to cool down our boiled wort, we then store it in our hot liquor tank for further use,” said HUB communications specialist Eric Steen. Both the brewery and kitchen focus on organic, sustainable practices.
For now, at least, the water news is good. The Clean Water Rule was officially adopted and formalized by President Barack Obama in May.
That won’t mean the end to challenges and legislative maneuvers, so supporting and/or taking the Clean Water Pledge will be more important than ever. You can find more information on the NRDC website: http://www.nrdc.org/water/brewers-for-clean-water/
