According to Nirupam, "It would be easier to shift the depot and casting yard to Dahisar as a land there belongs to the Centre. The present Charkop land has run into environmental hurdles turning the project into a non-starter since 2009 despite contracts being awarded." The Dahisar land belongs to the civil aviation department and can be easily made available for the project as it has not been included in any aviation expansion plans. Reliance had previously informed the State government that lack of environmental clearance to the Charkop depot, absence of permission from the aviation department for the Metro's elevated track in Juhu, huge network of underground and overhead utilities and no higher FSI for station's commercial development made the project financially unviable. On 13 November 2014, Reliance Infrastructure announced that it had terminated the agreement between the MMTPL and the Maharashtra government. RInfra stated, "Due to non-fulfilment of various critical obligations by Maharashtra government and Mumbai Metropolitan Region Development Authority (MMRDA), the project could not take off. Even after four years, despite the best efforts of the Maharashtra government, various project impediments could not be resolved." The MMRDA issued a statement confirming that the agreement was terminated with mutual consent. No party will bare any cost as a result of the termination and the state government will return a bank guarantee of 160 crore. The MMRDA also clarified that the Line 2 project had not been cancelled and will be constructed by the Mumbai Metro Railway Corp. Ltd (MMRCL) under an engineering, procurement and construction (EPC) model. In September 2013, the MMRDA appointed RITES to study the feasibility of constructing the proposed 32-km metro line underground. RITES also studied the feasibility of extending the corridor and merging the 7.5-km Charkop-Dahisar metro, proposed as a separate line, with this project. RITES submitted its final report to the MMRDA in the last week of May 2014, concluding that constructing the metro underground and extending it up to Dahisar was feasible. The merged Dahisar-Bandra-Mankhurd line would be 40.2 km long and have 37 underground stations. The estimated cost of construction of this line is 28,900 crore, 134% higher than the originally estimated costs of 7,660 crore for the Charkop-Bandra-Mankhurd line and 4,680 crore for the Charkop-Dahisar corridor. RITES proposed the construction of a major car depot at Oshiwara and a minor car depot at Mandalay, Mankhurd on sites that were a mix of publicly and privately held land.
