October the World Bank Group's International Finance Corporation (IFC) and Multilateral Investment Guarantee Agency (MIGA) released the final cumulative impact study for the two proposed pulp mill projects. Both institutions were confident that the findings demonstrated that the mills will comply with IFC and MIGA's environmental and social policies, while generating significant economic benefits for the Uruguayan economy. Also so called Hatfield Consultants, which had in March presented questioned the draft CIS, reviewed the final CIS, and confirmed the results of the final CIS. The more than two hundred pages study performed by EcoMetrix Incorporated concluded that the plans construction and operation posed no risk to air and water quality. In reaction to the study, the Gualeguaychú Assembly decided to block the international road again during the following long weekend (Columbus Day Weekend). The leaflets distributed for travellers described dire consequences for the life in Gualeguaychú (dioxin pollution, acid rain, increased incidence of cancer) when the mills start operations (the same accusations available in CEDHA homepages). Meanwhile, activists in Buenos Aires started a campaign calling Argentines to stay in Argentina for the summer vacations instead of going to Uruguay. The Argentine government and the provincial Entre Ríos government released a joint statement showing disagreement with the blockade, and laying the blame on the Assembly "for any harm that [the blockade] may cause to Argentine interests", but did not take any specific measures to prevent the blockade. The Assembly of Colón blocked International Road 135 as well, though only intermittently. During the weekend, Romina Picolotti, the Argentine Environment Secretary, sent a letter to IFC authorities claiming that the EcoMetrix study did not provide any new data, but employed those found in the environmental impact studies conducted for Botnia and ENCE, and that the section of the study devoted to the hydrological model was handled by an engineer who had previously been hired for Botnia's own study. Picolotti also claimed there were "substantial errors" in the study, such as exaggerating the flow of the Uruguay River and stating that it is 20 km wide, whereas no part of it is over 12 km wide. On 17 October, the IFC and MIGA announced that they will ask their Boards of Directors to approve IFC financing and MIGA guarantee support for Oy Metsä-Botnia's Orion pulp mill project in Uruguay. According to the IFC press release, "the decision to proceed was based on an extensive
