Our Goals

• Introduce students to writing an EA/EIS• Become familiar with the NEPA process• Gain experience with environmental

report writing

Community Based Learning

• Service and justice in the classroom

• Community partners • Real world experience

Regis University Mission

• Learners becoming leaders• “How ought we to live”• Jesuit ideals: Men and Women in

Service to Others

EIA as a Capstone

• Capstone Class• Culmination of past education• Future Career Path

Platte Valley Open Space

• Project: Writing PVOS EA• Combined community based

learning goals and professional goals as ENVS students

• Career preparation for graduates

Globeville History• The American Smelting and

Refining Company (ASARCO) Corporation opened its doors in the late 1800’s.

• ASARCO was a smelting plant that melted metal like arsenic, cadmium, copper, lead and zinc.

What is a Smelting Plant?

• How it works

• Smoke Stack Issues

Pro’s and Con’s

• Pro: Employment

• Con: Pollution

ASARCO Contaminants

• Lead

• Zinc

• Arsenic

• Cadmium

ASARCO Pollution EffectsASARCO Pollution Effects

• Being exposed the metallic fumes can cause a number of health issues.

Environmental Justice

• This applies to Globeville because:

– consisting mainly of minorities

– 1.3% vs. 5.1%

– 22.7%

(Globeville neighborhood, 2010).

ASARCO Lawsuit

• In recent years residents began to wonder how safe their land was

What is NEPA

• 1960’s “rise of environmental consciousness” from environmental works such as Rachel

Carson’s book “Silent Spring”• National Environmental Policy Act- enacted in

1969• “world’s first policy that protects the human

environment for future generations” (Eccelston, 2001)

NEPA

• NEPA has two titles– Title I- sets up procedural requirements that need

to be followed when implementing a federal action

– Title II- Creates the Council on Environmental Quality

• CEQ oversees NEPA

Flow Chart of the NEPA Process

Some Examples:

•Soil•Native vegetation

•Socioeconomic factors •Surface and ground water

•Aesthetics•Air quality

•Impact on surrounding areas•Wildlife

What Does NEPA Protect/ Consider?

Environmental Assessment (EA) vs. Environmental Impact Statement (EIS)

• What is an EA?– Used to analyze the environmental impacts of

proposed federal actions.• What is an EIS?

– More extensive than an EA

CDPHE v. ASARCO

CDPHE: Colorado Department of Public Health and Environment

CERCLA: Comprehensive Environmental Response Compensation and Liability Act

The NPL: National Priorities List

• ASARCO settles– Then goes bankrupt

• Why the site is stuck

Timeline of the Globeville Site Relating to the ASARCO Contamination

• 1987- CDPHE and ASARCO made an agreement in to determine the extent of the sites contamination

• May 1993- EPA proposed the Globeville site for the NPL( National Priorities Lists)

• July 1993 ASARCO settle with CDPHE to pay for site, they agreeded to pay for sites cleanup with the oversight of CDPHE

• 2002- Residential cleanup completed

Where are we Now?

• The Globeville community taken site into their own hands.

• With the help of Groundwork Denver the community is working to change the Oletski Valley into open space.

• Our class wrote an EA in order to assess the proposed actions to the Globeville site. We believe these actions will result in a Finding of No Significant Impact (FONSI)

Current physical description • PVOS is an open field with houses at the very

end with some vegetation and power poles through out the site.

• Surrounded by graffiti on fences and poles.

Hydrology

• The area floods often, and there is a small patch on the south side that tends to collect pools of water.

Surroundings

• The train tracks, residential housing, and industrial buildings border PVOS.

• Part of the site is scattered with trash, and residents were not seen using the area.

59%

View and Noise

• The site overlooks the Denver skyline, and the Rocky mountains.

• The low noise level potentially creates a pleasant environment, with some clean up efforts.

Outcomes from Environmental Assessment

• As a class we have learned some of the advantages and restraints of preparing an Environmental Assessment.

• Comprehensive documentations of the Platte Valley Open Space, and some proposed actions for the remediated area.

• Knowledge regarding the current state of the Globeville neighborhood, and its long deep-rooted history.

Conclusions and Suggestions

• Proposals that benefit the community such as walking paths, corridor between parks, trash clean-up, raised bed gardens, and others.

• All proposals are done with the local community in mind.

What’s Next for the PVOS

• We hope to see the open space utilized in some fashion that benefits the local community.

• Some community members put in large amounts of time and effort to fight the case against ASARCO, and the open space should be one of the many rewards of success.
