The current rules are effective for all work that is completed by December 31, 2008.
Beginning January 1, 2009, the new rules are effective, except the requirement to have either an irrigator or irrigation technician on-site during the installation of an irrigation system is effective on January 1, 2010.
Irrigation systems that are completed on or after January 1, 2009, should meet the requirements of the new rules.
