The Colorado Department of ,Agriculture has responsibilities in two main areas
concerning water quality. The Chemigation Act of 1967 gave the Department the
responsibility to address the process whereby chemicals are applied to the
land or crops in or with water through a closed irrigation system. A
permitting process has been established if an irrigator applies chemicals
through a closed irrigation system such as a circular sprinkler. The second,
area concerning water quality gives the Department responsibility in the
designation of geographic areas where there is a significant risk of
contamination of groundwater from agricultural activities conducted at or near
the land surface. This activity will be completed in cooperation with the ",
Department of Health and Cooperative Extension service.,

IV. Local proarams and Authorities for Control of Nonooint,Sources

~~
r.~

Local programs, ordinances and voluntary efforts are crucial to the
implementation of many nonpoint source improvement projects. On ground
construction and long term monitoring and maintenance will, in many cases, be
the responsibility of local entities. Additionally, local ordinance and
education programs can do much to prevent nonpoint source problems.

A. Municioal Ordinances and Authorities

'.:;

Local municipalities can provide assistance to prevent nonpoint sOurce
pollution through several avenues. Municipalities may pass ordinances to
controlnonpoint sources'. In particular enabling legislation found in CRS .
29-20-101 allows local municipalities to control land use activities through
regulations. These authorities can be very helpful in controlling erosion
from land disturbance activities.

Additionally local governments such as towns, cities, counties, special
districts, soil conservation districts, and water conservancy districts may
enter contracts and therefore accept grants and carry out nonpoint source
correction projects. Section 319 also allows "soft match" or "in kind
services" as the 40% of local matching funds. This provision may be very
helpful if local governments are willing to provide these services in ,lieu of
hard cash for matching federal grants.

Many volunteer, conservation, and environmental groups have interests in
controlling nonpoint sources. Groups such as Trout Unlimited, the sierra
Club, the Isaac Walton League, the Colorado Volunteers and others may sponsor
project, or provide a source of matching "in kind" services for construction
projects. This level of support, interest, and help is essential in carrying
out successful nonpoint source projects.
