Hogan opposed a new "phosphorus management tool" that former Gov. Martin O'Malley attempted to get approved just before leaving office. Hogan stopped the regulations and promised farmers that he would listen to their concerns. Hogan's alternate plan provided more time for farmers to implement the pollution-cutting requirements. But Sen. Paul Pinsky, a Prince George's County Democrat, introduced a bill to implement O'Malley's plan and that bill was making its way through the legislature. Pinsky argued that Hogan's plan included too many delays in implementation.
