Esta tasa son las citaciones registradas divididas entre las horas de inspección de la MSHA, por cada 100 horas. Refleja el esfuerzo de inspección, no el tamaño de la mina ni la producción.Rockfield Plant tiene $52K en multas propuestas de MSHA y $2K pendientes en 2 expedientes impugnados.
ⓘ
Las diferencias entre las multas propuestas y las pagadas reflejan tanto acuerdos y reducciones en conferencia como montos aun adeudados. Pendiente es el saldo que se debe actualmente.ⓘ
Las proporciones se calculan sobre las citaciones que llevan la codificación de gravedad y negligencia de la MSHA; una pequeña parte de los registros no está codificada.ⓘ
Impugnar una citación ante la Comisión Federal de Revisión de Seguridad y Salud Minera es un derecho legal. Estas cifras presentan los resultados públicos de ese proceso, según el archivo de Violaciones Impugnadas de MSHA.- Conciliadas 4 · 80%
- Anuladas o retiradas 1 · 20%
ⓘ
Una citación Significativa y Sustancial cuenta como sobreviviente cuando la conciliación o la decisión del juez mantuvo la designación, o cuando la impugnación fue desestimada o quedó en rebeldía y la citación quedó como emitida. Las citaciones anuladas o retiradas, y las conciliaciones que quitaron la designación, cuentan en contra.ⓘ

Rockfield Plant se ubica en Fresno County, California, donde la categoría minera del Censo representa el 0.1% del empleo del condado.
ⓘ
Las cifras del condado provienen de la Encuesta sobre la Comunidad Estadounidense de la Oficina del Censo de EE. UU., estimaciones quinquenales agrupadas, por lo que la edición de 2023 abarca de 2019 a 2023. La categoría del Censo es 'minería, explotación de canteras y extracción de petróleo y gas', que es más amplia que la jurisdicción de la MSHA e incluye a trabajadores de petróleo y gas que ninguna mina emplea. Estas cifras describen el condado circundante, no esta mina, y no son un factor en ningún incidente específico.ⓘ
