Certified wastewater operators in MA are required to renew their certification every two years, with renewals due by December 31st of odd-numbered years. Active operators are required to obtain twenty training contact hours (TCHs) over the two-year renewal period. If you are like many other operators, you might be scrambling to complete your TCH criteria by the end of the year.
