Officials say OP3 has already been leveraged for public benefit, including when participating retailers helped get extra water to the Toledo area in August when toxins produced by algae in Lake Erie fouled the tap water for 400,000 people. Businesses and associations receive no financial incentives for participating in OP3 but can benefit from quick access to information from the government side of planning or response efforts, Ohio Homeland Security Director Richard Baron said. Other partners signed on include Ohio's largest electricity providers, a half-dozen business associations and a variety of retailers, hospitals, insurers, communications companies, restaurants, banks and manufacturers.
