This study is being performed based on the U.S. Toxic Substances Control Act (TSCA) Section

4 Test Rule and the regulations set forth under 40 CFR 799.5087.



### Special Conditions

Study specific parameters:

GSP Section 1.1 Guidelines / Regulations:

The study will be conducted according to the following internationally accepted guidelines and

recommendations:

**•** OECD Guidelines for Testing of Chemicals (1992) No 203, “Fish Acute Toxicity Test”

GSP Section 3.2 Test System:

The study will be conducted using Rainbow Trout ( Oncorhynchus mykiss )

GSP Section 3.3 Test Water:

The study will be conducted using reconstituted water

GSP Section 3.7 Study Design:

The study will be conducted using 7 fish per test concentration.

Any pH adjustments of the exposure solutions will be conducted according to section 14 of

OECD 203 details of which will be included in the final test report.

If measured concentrations are ± 20% of the nominal concentrations, results will be based on

nominal concentrations. If measured concentrations are not ± 20% of nominal concentrations

, results will be based on geometric mean measured concentration s.

The study report will provide a detailed description of the analytical method that will be

developed prior to and utilized during the test.

All elements described in item 23 of OECD 203 will be included in the final test report.

Particulate matter concentration, chemical oxygen demand (COD), total organic carbonHarlan Study Number: 41401173 Study Specific Supplement Page 3

(TOC), hardness, alkalinity and conductivity of the dilution water will be determined at the

start of the study.
