The addendum adds Appendix A to the solicitation documents and provides answers to previously submitted questions from potential bidders.

ATTACHMENT 1
Q1. I assume Contech Certification is required?
A1. Yes, Contech Certification is required.
Q2. Can you provide more detail on the WQ monitoring required for Task 7? Are the parameters the same for monthly, bimonthly and annual?
A2. WQ monitoring is conducted annually for basic parameters (nutrients, pH, etc) -treatment is administered following based on those test results. Typical for nutrients or alkalinity. Routine monthly/bimonthly monitoring and treatment activities do not include data collection and is visual identification and treatment of invasives.
Q3. I have a quick follow up question to make sure I heard you correctly. You said we can submit a bid on just a line-item(s) and not an entire task, correct?
A3. No, that is not correct. You must complete pricing for an entire task. You do not need to submit pricing for all tasks.
