Abstract
This report, which replaces CRS Report RL31051, provides updated information on interstate shipment of municipal solid waste (MSW).Since the late 1980s, Congress has considered, but not enacted, numerous bills that would allow states to impose restrictions on interstate waste shipments, a step the Constitution prohibits in the absence of congressional authorization.Over this period, there has been a continuing interest in knowing how much waste is being shipped across state lines for disposal, and what states might be affected by proposed legislation.This report provides data useful in addressing these questions.Total interstate waste shipments continue to rise due to the closure of older local landfills and the increasing consolidation of the waste management industry.About 35 million tons of municipal solid waste crossed state lines for disposal in 2001, an increase of 9.4% over 2000.Waste imports have grown each year since CRS began tracking them in the early 1990s, and now represent 21.6% of all municipal solid waste disposed at landfills and waste combustion facilities.In the last eight years, reported imports have increased 141%.Pennsylvania remains, by far, the largest waste importer.The state received 10.7 million tons of municipal solid waste and 1.9 million tons of other nonhazardous waste from out of state in 2001, more than 30% of the national total for interstate shipments.Virginia, the second largest importer, received 4.1 million tons, 62% less than the amount received by Pennsylvania.Michigan, the third largest importer, imported 3.6 million tons of MSW in fiscal year 2001; waste imports to Michigan have doubled since 1999.Twenty-three states had increased imports in the current report -the largest increases occurring in Pennsylvania and Michigan.In all, eight states reported imports that exceeded one million tons.While waste imports increased overall, several states (including New Hampshire, South Carolina, Connecticut, Arizona, and Washington) reported sharp declines in waste imports.New York remains the largest exporter of waste, with New Jersey and Illinois in second and third place, respectively.Four states (New York, New Jersey, Illinois, and Maryland) account for more than half the national total of waste exports. 1 Legislation on interstate shipment of waste has been introduced in every Congress since the 100 th .In the 104 th Congress, the Senate passed S. 534.The bill would have granted states authority to restrict new shipments of municipal solid waste from out of state, if requested by an affected local government.In the 103 rd Congress, both the House and Senate passed interstate waste legislation (H.R. 4779 and S. 2345), but lack of agreement on common language prevented enactment.For a discussion of the issues addressed in these bills, see CRS Report RS20106, Interstate Waste Transport: Legislative Issues. 2 This report replaces Interstate Shipment of Municipal Solid Waste: 2001 Update, CRS Report RL31051.Earlier reports, now out of print but available directly from the author, were Interstate Shipment of Municipal Solid Waste: 2000 Update, CRS Report RL30409,

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
