I. Target audience(s)
Loggers, maintenance people, mechanics, fuel jobbers, etc.
II. Learning Objective(S)/Purpose
Impress upon the audience that preventing spills should be their first
consideration. Not only will it save time and money required for cleaning
up a spill, it also saves money by not losing product and necessary repairs
of malfunctioning equipment. Well maintained and regularly inspected
equipment is worth the, “ounce of prevention”.
No matter how well equipment is maintained, spills will occasionally
happen. Being prepared for spills will help to minimize their severity so
that cleanup will be less complicated and more effective. Clean-up kits are
discussed as helpful preparedness tools. Spill reporting requirements are
discussed.
Spill cleanup options depending upon the type, volume and site conditions
are discussed along with treatment/disposal options for spilled wastes.
[Page 90, last bullet, of the FMG book is misleading concerning when
you may thin-spread petroleum contaminated soil.]
Enforcement for unreported and/or inadequate cleanups are possibilities
and may include monetary penalties. Having to remobilize to a site to
conduct a cleanup adds to overall costs and land owners may decide to
restrict further use of their properties to loggers that leave a mess.
III. Presentation Outline
A. Prevent spills from occurring.
Maintain equipment to prevent failures that could cause spills.
Inspect equipment for small drips or spills and worn hoses or parts that
may soon fail. Replace worn equipment before failures.
Take care when adding or removing products and fuels.
B. Be prepared for when spills do occur.
Minimize the volume of spills by stopping releases as soon as
possible.
Capture or contain spills. Catching spills onto drip pans or by using
absorbent material will minimize spills to the ground. When a spill is
flowing away from a release site, try to contain it with a berm, ditch or
absorbent materials.
Special care must be taken from petroleum reaching surface waters
including streams. When such impacts do occur, floating booms and
absorbent pads can be used to contain and collect product and even
sheens. Dispersants in surface waters should never be used because
they make the petroleum more toxic to the water column.
Reporting petroleum spills of 5 gallons or more is required. If the
quantity is unknown, there is no problem in reporting estimated
volumes. If no assistance is needed, state follow-up is unlikely. Also,
the State Duty Officer can connect callers to the MPCA on-call person
who can offer cleanup advice and suggestions.
C. Cleanup options are discussed.
Types of petroleum and their ease of natural degradation is discussed.
Gasoline volatilizes quicker than diesel or hydraulic oil.
Patches of stained soil can usually be scrapped up and spread on site
or even raked and broken up so that natural break down can more
quickly occur.
Petroleum contaminated soil of 10-cublic yards or less can usually be
spread on site. Discussion with the property owner as well site
conditions for thin-spreading and ways to maximize the effectiveness
of this treatment method is discussed.
Absorbent pads and boom that are not completely saturated can
usually be let to dry in the sun and reused. Disposal of saturated used
absorbent material can usually be handled through the company that
receives used oil and other similar wastes.
On-site burning of waste from spills is prohibited.
D. Enforcement.
Spills that were unreported when required or were not adequately
cleaned could result in enforcement actions, including penalties, by the
Minnesota Pollution Control Agency (MPCA).
As part of many enforcement actions, corrective action is often
required which would mean returning to the site to conduct an
adequate cleanup.
Outside of formal MPCA enforcement actions, property owners where
messes are left may decide to prohibit further logging contracts on their
properties. Also, it is poor public relations to anyone that may come
across spills left at logging sites.
IV. Discussion Questions
Can you afford to waste product from your equipment or containers?
What are some ways to prevent spills from occurring in the first place?
What are some ways to stop and contain a release? What types of
equipment or supplies could you use to minimize the size and extent of
a release?
What are some ways to cleanup small spills at your site? Who should
you call to report a spill or just to ask advice about spill cleanup?
Are there any consequences for not conducting a cleanup after a spill?
V. Frequently Asked Questions
Petroleum comes from the ground in the first place, why worry about
spills?
In addition to fire hazard and potential human health impacts, spills
cause damage to the environment. Petroleum spills could take a very
long time to degrade when left in a concentrated form. Spills can
impact ground water. Spills that impact surface water can make the
water column toxic to biota in the water column.
Where can we get rid of waste product that we collect after a spill?
Most companies that accept used oil also have that capability to accept
used absorbent material. If they don’t, they should know someone who
can.
VI. Group Activity / Case Studies
Let’s say that you have an elevated 55-gallon drum at your site used to
store diesel to fuel your equipment. The drum gets knocked over when
moving a skidder and the drum starts leaking product down a slope
towards a stream.
What are some suggestions for preventing this release in the first
place? Ways to minimize the amount and extent of the release? What
are some suggested for cleanup options?
Suggestions may include: better planning regarding where the fuel
drum should be located in the first place, i.e. away from traffic areas
where it may get hit and away from sensitive or problematic areas
(near a slope) if it does tip or fail; make the drum more visible so it is
easier to avoid; store spill response equipment near the drum to be
better prepared for a release; if flowing down a slope, try to get in front
of the flow as soon as possible to contain product with a berm or ditch;
if any spill reaches a surface water, try to contain with absorbent or
containment boom and collect with absorbent pads.
VII. Resources
Spill kit, absorbent pads and boom, small containment box, rake, and
Duty Officer phone number.

Field sites for these presentations should be at the types of areas
where fuel storage, product storage and equipment maintenance may
typically occur.
