(e) The following notes shall apply to Table 1610-1:
1. (1) Except for (2) and (3), below, the detection limit for all the analyses shall be at or below the detection limits specific in the tables;
2. (2) If the percent solids in a septage solids sample is below 5%, the results shall be reported in mg/l and the detection limits shall be appropriate to the methodology specified in the tables for a water matrix;
3. (3) If the detection limit specified in the tables can not be achieved by the methodology listed, the department shall accept such detection limits which are routinely achievable; and
4. (4) The designation “na” means “not applicable”.
(f) The EQ certification holder shall analyze the solids from its treatment facility at the frequencies specified in Table 1610-3, below, in accordance with the analytical methods and detection limits specified:

(g) Additional testing shall be required by the department when results of testing conducted by the EQ certification holder or the department show that the requirements in Env-Wq 1610.03 have not been met.
(h) If additional testing is required under (g), above, the EQ certification holder and all end users shall cease use and distribution of the EQ solids until the additional testing, performed in accordance with (j), below, demonstrates that the EQ solids is acceptable to use according to the standards of Env-Wq 1610.03.
(i) No storage of EQ solids shall be allowed off the facility footprint while the additional testing performed under (h), above, is completed.
(j) The EQ certification holder shall undertake the following in accordance with the analytical procedures specified in (d), above:
1. (1) Collect and analyze representative samples of solids from each storage structure for the constituent(s) of concern and submit results to the department for review and approval prior to further distribution;
2. (2) Increase the frequency of testing at the treatment facility for the compound(s) of concern to weekly; continue the weekly sampling until 4 successive weeks show that the concentration of the constituent(s) of concern meets the standards in Env-Wq 1610.03, as determined by the department; and
3. (3) After complying with (2) above, resume distribution and increase sampling frequency specified in Env-Wq 1610.05 to monthly for the constituent(s) of concern for 6 months.
(k) The department shall waive testing of a constituent if it determines, based on all available information, that the constituent is not present in the EQ solids.
