Project Development Objective (PDO)
Original PDO
The overall development objective of the proposed APL program supports the Government's Integrated Basin Cleanup
whilesimultaneously improving sanitary conditions along the banks of La Plata River and providing a long-term and
cost-effectivesolution for safe disposal of wastewater from the Buenos Aires Metropolitan Area (AySAs concession
area). The two stage APL programthat contributes to this objective and the allocation of works and activities under
each APL has been specifically designed toensure that APL-1 can be free-standing, with no stranded assets at the end
of the first stage.

The project (APL-1) development objectives contribute to the overall program development objective by (i) improving
sewerageservices in the M-R River Basin and other parts of the Province and City of Buenos Aires by expanding
transport and treatmentcapacity; (ii) supporting a reduction of industrial discharges to the M-R River, through the
provision of industrial conversiongrants to small and medium enterprises; (iii) promoting improved decision-making for
environmentally-sustainable land use anddrainage planning, and piloting urban drainage and land use investments, in
the M-R River Basin; and (iv) strengthening ACUMAR#sinstitutional framework for ongoing and sustainable clean-up of
the M-R River Basin.

II. SUMMARY OF PROJECT STATUS AND PROPOSED CHANGES

 The project has a moderately satisfactory rating for its overall implementation progress and its progress towards
 achievement of its PDO. The project is expected to complete most of its activities before its current closing date
 (September 30, 2024) and thus achieve most of PDOs.

 Two ongoing contracts facing implementation delays are the Riachuelo Wastewater Treatment Plant (WWTP) and the
 industrial WWTP. Current delays of these two contracts are mainly caused by difficulties in the payment,
 transportation, and customs clearance of imported electromechanical equipment. Of the two, the Riachuelo WWTP
 contract is expected to be completed before the project's current closing date but the industrial WWTP contract is
 expected to be completed shortly after the project's current closing date. Delay in the industrial WWTP contract puts
 at risk the achievement of the PDO of reducing pollution load discharges. The Bank has been working with the Project
 Implementation Unit (PIU) and AySA to find practical solutions to address the import challenges, to ensure timely
 completion of the Riachuelo WWTP, and to avoid any further implementation delays of the Industrial WWTP contract.

 In April 2023, the Bank's supervision mission confirmed that (a) there would be savings from the Riachuelo WWTP
 contract financed by the Second Additional Financing (AF) Loan of the project; and (b) there are additional funding
 requirements for remaining contracts under Component 2 Industrial Pollution Abatement and Component 3
 Environmental Territorial Management. As such, the PIU proposed that such saving be relocated to cover financial
 gaps for the remaining contracts under Components 2 and 3.

 On May 12, 2023, the Government of Argentina sent the Bank its official request (see the attachment) to restructure
 the project by expanding one disbursement category (Category 1) of the Second AF Loan to support the remaining
 contracts of Components 2 and 3. The proposed restructuring, entails a change in disbursement Category 1 by
 changing what this category financing, as it was limited to fund some activities under Component 1, by including the
 possibility to fund Works under Components 2 and 3. No reallocation of loan proceeds, or changnes to funding
 percentages are foreseen.

 The change will enable the government to utilize expected savings of the Second AF Loan to cover financing gaps, and
 ensure timely completion, of the remaining contracts of Components 2 and 3. This proposed restructuring will have no
 impacts on other aspects of project implementation.
