The government granted construction material companies 60 days to extract aggregate from riversides. The Academy of Science protested that the government did not adhere to the recommendations made by the commission it called to study the problem of the effect of removing construction materials from Dominican rivers. The Academy of Science said that the government had established the areas where the materials could be extracted, but in the public announcement instead authorized extraction from all rivers. The agreement calls for a 60-day period, but Minister of Public Works Diandino Peña says this could be extended to 30 days or more as needed. Minister of Public Works emphasized that the pace of public and private construction works could not be stopped.
