STEP enrollment includes a rigorous technical and environmental screening, but is not a type ap-proval process. STATISTICS All systems using active substances require IMO Basic & Final Approval. These systems must also comply with all applicable requirements of the EPA VG and CA Section 401 CertiÞ cation of the VGP. According to CSLC, classiÞ cation society require- ments play a role and must be taken into account when selecting a BWMS. But, they say, most of the class approvals are for safety or mechanical issues and the CSLC focus has been on biological efÞ cacy of the systems only. It?s not easy being green. Which one should you use? That depends on literally 1,000 variables. YouÕll need to make up your mind soon. Turn to page 33 of this edition for help.62 | Maritime Professional | 3Q 2012
