2. Reassessment of EUN for Laboratory and Analytical Use of CTC (1) Party 2015 Nominated 2015 Recommended China9080 CTOC recommends the EUN of 80 tonnes of CTC for 2015. Given the timing presented for the approval and introduction of the new testing standards in China, an update of the “status” for any further approval could be submitted together with a request in 2015 for a possible 2016 essential use exemption, while indicating when a final request for CTC for this application will be made.

3. China requested an EUN for CTC Laboratory and Analytical uses (“testing of oil, grease and total petroleum hydrocarbons in water”). CTOC was unable to recommend the China EUN due to the following concerns: the relationship of this nomination to the CTC Phase-Out Plan signed between China and the Multilateral Fund the significant delays in drafting, submitting and implementing the revised standards, as described in the nomination, even though ODS- free alternative methods have been available for 15 years the justification for the 90 tonnes of CTC to conduct the water analysis After bilateral consultations at OEWG-34, China agreed to submit the additional information requested by CTOC, which was received on September 5, 2014. 3 Reassessment of EUN for Laboratory and Analytical Use of CTC (2)

4. The agreements between China and the MLF do not include the phase-out of CTC in Laboratory and Analytical uses, and China has been consistent with Decision XXIII/6 in its essential use nomination of CTC for this application China cannot adopt the methods used in other countries as it has different requirements and conditions for this testing, i.e., concentration of impurities in the water, detection limits, and the purity of the solvent for extraction China is now applying the top-down calculation method to estimate the total volume of CTC usage China has also agreed to reduce the nominated quantities by 10 tonnes for 2015 by accelerating the transition to new technologies 4 Reassessment of EUN for Laboratory and Analytical Use of CTC (3)
