Seed Testing: Seed shall be tested within 9 months prior to planting. Testing shall be performed by a State Seed Lab, Commercial Seed Testing Lab, or a registered member of the Society of Commercial Seed Analysts (Registered Seed Technologist). A certified test report shall be furnished prior to the start of seeding operations. If the seed is not planted within the 9 month period, the Contractor shall have the seed retested (as described above) for dormant seed, hard seed and germination and a new certified test report shall be furnished prior to starting seeding operations. The retest will be based on a sample obtained from the seed out of compliance. A certified test report will not be required on projects where the plans quantity of seed is 100 pounds ( 45 kilograms) or less.

Section 730.4 - Page 361 - Delete the last sentence in the last paragraph and replace with the following:

If the seed has been retested based on Section 730.2 C., the retested value will be used in determining PLS.
