Environmental Expenses
1997-2005
Total Capital Projects $29.7 million
Environmental Projects 5.59 million (18.8% of total capital projects)
FY 2004 Environmental Expenses
$2,750,000 (this includes all mud, limestone, rock and trash, air pollution control,
wastewater processing, permitting and other expenses)
“But there are limits to how responsibly companies
can behave when behaving responsibly raises their
costs and consumers are unwilling to pay higher
prices. The most important constraint on the
pursuit of virtue is the market”
David Vogel, Professor. Haas School of Business,
University of California, Berkeley and author of

Corporate Social Responsibility

Strategies for Handling
Environmental Compliance
• Prevention
• Treatment for Reuse
or Release
• Release to the
Environment
• Storage
Prevention
(avoids the problem of pollutants)
• Goes hand-in hand
with cost reduction
• Fuel efficiency
• Lower Wastewater
Generation
• Can take large capital
investment
• Steam pulp dryer
• Dry beet handling
Treatment for Reuse or Release
(Removes or reduces pollutants to acceptable levels)
• Treatment for Reuse
• wastewater
• waste lime
• Treatment for Release
• Stack Gasses
• wastewater
• Treatment systems often
generate their own wastes
• dust (particle removal)
• sludge (wastewater
treatment)
Release into Environment
• Limited Capacity to
accept Pollutants
• Highly Regulated
• Carefully Monitored
Almost all Discharges Are
Regulated
• EPA
• State Department of
Health
• Tribal Environmental
Council
• County Board
• City Council
Penalties for not Obeying
Environmental Rules
•
•
•
•
•
Civil and Criminal
Fines
Jail
Disqualification
Escalating
Discharging to the Environment
is Costly
• Large Amount of Material
• Compliance Costs
•
•
•
•
Permitting
Pre-discharge costs
Discharge monitoring
Post-discharge costs
• Fines if there are problems
Temporary and Permanent Storage
(Staging Areas, Landfills and Ponds)
• Ownership and
Operations
• Permitting
• Ongoing Care
• Liability
Strategy for Environmental Protection
must Balance many Issues
• Balance Costs and
Benefits
• Should fit into larger
corporate strategy
• Should consider
outside stakeholders
• Should consider shortand long-term
consequences
Environmental Stewardship is the
Right Thing
• Protects Nature
• Good Neighbor
• Reduces Expenses
(can make money)
• Prevents Trouble
• Part of the Job
