Stage 2
vapor recovery systems on gasoline dispensers have been required in
southeastern Wisconsin for decades. That will be changing due to a May
16, 2012 finding by the U.S. Environmental Protection Agency (EPA) that
onboard refueling vapor recovery (ORVR) technology is in widespread use
throughout the motor vehicle fleet. This finding by EPA allows states,
including Wisconsin, to no longer require Stage 2 vapor recovery.
Stage
2 vapor recovery is a control technology located at individual gas
stations. The system involves capturing and controlling gasoline vapors
when a vehicle is being fueled at the pump. The system uses special
dispensing nozzles that collect the vapors and pump them back into the
storage tank below ground, instead of releasing them into the air.
Newer
vehicles are equipped with ORVR control technology. This essentially
serves the same purpose as Stage 2 vapor recovery. Fuel vapors from the
vehicle gas taking are captured during refueling and travel to an
activated carbon pack canister within the vehicle, which absorbs the
vapor.
The
Department of Natural Resources (DNR) has been working collaboratively
with the Department of Safety and Professional Services (DSPS)
throughout the Stage 2 vapor recovery decommissioning process and has
developed the following forms (PDF) to assist gasoline stations
considering decommissioning:
In
addition, DNR has developed a draft State Implementation Plan (SIP) to
address the change in the Stage 2 Vapor Recovery requirements. The
purpose of the SIP is to get formal approval from EPA for the proposed
discontinuation of the program. A copy of the draft SIP can be found at http://dnr.wi.gov/topic/AirQuality/.
DNR will hold a public hearing on this document on October 8, 2012 in
Waukesha and will be accepting public comment on it until October 12,
2012.

If a chemist has never been in a lab accident, he has been lucky. Of
course luck is more likely to come to those whose mentors have learned
from bad experiences and to those who have taken preventive measures
seriously, despite their anal nature. Chemical reactions create products
with behaviors that differ from those of the ingredients. That's what
makes them intriguing, and it's also what makes them potentially
dangerous. No matter how simple and controllable a reaction seems on
paper, when it's carried out in real life, the exact conditions
determine its rate. And when gases or acids acquire too much kinetic
energy, no one wants eyes, lungs and flesh in their way.
As an
adolescent I played with my chemicals more than my instructors did.
Rarely did they carry out demonstrations while lecturing. Seldom did
they deviate from the tight parameters of cookbook labs. So I
unconsciously associated accidents with amateurs or with large scale
industrial processes. But after a freshman year of chemistry, I got my
first summer job in the lab after a metallurgical company did not rehire
a chemistry student previously involved in a serious analytical lab
accident. (More.....)

Titled
"Standard Guide For Commercial Entrance Matting In Reducing Slips, Trips
And Falls," it addresses mats and runners in commercial facilities.
The American National Standards Institute B101 Committee on Slip,
Trip and Fall Prevention has released the latest in its line of walkway
safety standards: ANSI/NFSI B101.6-2012, "Standard Guide For Commercial
Entrance Matting In Reducing Slips, Trips And Falls." It will help
building managers eliminate slip-and-fall hazards including dirt,
moisture, and contaminants.
