Environmental Manager

Environmental Department

Our mission is to create cleaner safer neighborhoods in which we live by working together with the Environmental Protection Agency to improve our local environmental quality.


Our water quality program enables us to control, prevent, and eliminate water pollution as well as to educate tribal members and the general public. Our current and past projects are as follows:


  • Developing and implementing comprehensive water quality monitoring programs.
  • Hiring program staff and purchasing equipment and supplies.
  • Conducting and reporting on water quality assessments.
  • Developing and implementing water quality ordinances and tribal and EPA-approved water quality standards and gaining TAS under CWA section 303(c) and section 401.
  • Developing water quality and geographic information system databases to track changes in water quality and ensure consistency in data management.
  • Attending trainings, workshops, and other events to build and share technical knowledge.
  • Conducting training and educational outreach to tribal members.
  • Identifying nonpoint sources of pollution.
  • Developing nonpoint source assessment reports and management plans.
  • Gaining TAS for CWA section 319 (nonpoint source) funding.

Air Quality 



Air pollution has been a growing concern among the community and experts alike. In efforts to mitigate the problem, accurately measuring air quality forms the foundation on which the means to confront this problem rests. Through data provided by these measurements, it is made possible to track both progress and actions needed in cleaning the air and meeting health-based standards effectively.




For California, the standards of Air Quality are defined by clean air and the pollutants that threaten the Air Quality. These standards differ dependent upon the pollutant in question and are set by the U.S. EPA and the ARB. Through standards, safe outdoor pollutant levels for the community are established.




Pollutants effect not only the Air Quality, but also the lives of Californians that are projected, by the data gathered, to have breathed unhealthy levels of one or more pollutants over the course of one year.




Criteria pollutants are the pollutants for which standards have been set and have been determined to be harmful to the community, in particular the most sensitive groups. In California, ten pollutants are identified as criteria pollutants including, ozone, particulate matter less than 2.5 microns, particulate matter less than 10 microns, nitrogen oxides, carbon monoxide, sulfur oxide, lead, hydrogen sulfide, sulfate, and vinyl chloride.



Toxic air contaminants (TAC) are pollutants that can cause serious long-term effects even at low levels. Examples of serious side-effects of TAC pollutants include cancer, reproductive and developmental effects, and neurological effects. TACs differ from the common or criteria air pollutants in that they have no known safe levels as they may accumulate in the body with repeated long-term exposure. Over 200 pollutants have been identified as TACs and are periodically measured along with criteria pollutants to determine whether efforts taken to clean the air are efficient in reducing air pollution.
