For the first time ever, Oregonians can have grocers make same-day deliveries of unlimited amounts of beer and wine to their homes, the Oregon Liquor Control Commission decided Thursday.

The orders must be placed by 9 a.m. and delivered by 9 p.m. the same day.

The new rule, requested by Safeway, takes effect June 29 and replaces temporary rules that have allowed grocers to make limited amounts of same-day beer and wine deliveries since January.

Judy Cushing, president of Oregon Partnership, a nonprofit that promotes drug and alcohol awareness, blasted the commission's 5-0 vote, saying it will contribute to Oregon's "alarmingly high rates of teen drinking" by opening up new ways for youths to get access to and abuse alcohol.

"The science is so clear on reducing underage drinking," Cushing said. "Access and availability are at the top of the list, but now we're really making it easy."

She said the commission should have studied the rule change rather than fast-tracking it under pressure from grocers.

OLCC officials said public safety is an important part of the agency's mission and of any rules adopted by the commission, including the home-delivery rule.

OLCC Chairman Phil Lang said he doesn't think the change will increase underage drinking.

"I personally don't think it's going to change what the practices are by much, if at all," Lang said. "The fact is, if there's a 21-year-old in the group, they can take their car or pickup to the store and buy an unlimited amount."

The change is part of a shift in the availability of home beer and wine deliveries in Oregon. Until this year, the only businesses that could make same-day home deliveries were those serving meals, such as pizza outlets. Grocers were only allowed to deliver beer and wine ordered the previous day.

Since January, however, temporary OLCC rules allowed grocers to deliver up to five gallons of beer or two cases of wine if the order was placed by 4 p.m. and delivered by 9 p.m. the same day.

Thursday's rule change makes those provisions permanent starting June 29. In addition, the unlimited beer and wine deliveries will be allowed on the same day if they're ordered by 9 a.m. Amounts over the five-gallon, two-case limit will be allowed until 4 p.m. as long as the alcohol makes up no more than 25 percent of the total order's cost.

Oregon law does not allow home deliveries of hard liquor, which has to be purchased in one of the more than 240 state-operated liquor stores.

Dan Floyd, a lobbyist for Safeway, said the new rules wouldn't change much for the chain's customers because customers can't get grocery orders delivered the same day if they are placed after 9 a.m., regardless of whether they include beer or wine.

He noted that the chain doesn't sell beer or wine deliveries to people who are visibly intoxicated or aren't age 21 or older. In addition to the OLCC requirement that an adult show identification and sign for same-day deliveries, Safeway drivers also are instructed to take down the driver's license number of the purchaser.

He said Safeway has been making home deliveries of beer and wine for seven years without incident.

Cushing, however, said she has concerns about the same-day home deliveries, including situations where deliveries would go to a fraternity or sorority that has a mix of underage and legal-drinking-age students, or in situations where young adults have false IDs that would give them the appearance of being able to legally order alcohol.
